The effect which now bears his name, was discovered in 1958 by Rudolf Mössbauer at the Technical University of Munich. At first, this appeared to be a phenomenon related to nuclear energy levels that provided some information about excited state lifetimes and quantum properties. However, it soon became apparent that Mössbauer spectroscopy had applications in such diverse fields as general relativity, solid state physics, chemistry, materials science, biology, medical physics, archeology and art. It is the extreme sensitivity of the effect to the atomic environment around the probe atom as well as the ability to apply the technique to some interesting and important elements, most notably iron, that is responsible for the Mössbauer effect's extensive use. The present volume reviews the historical development of the Mössbauer effect, the experimental details, the basic physics of hyperfine interactions and some of the numerous applications of Mössbauer effect spectroscopy.

Tutorials on Mössbauer Spectroscopy Since the discovery of the Mössbauer Effect many excellent books have been published for researchers and for doctoral and master level students. However, there appears to be no textbook available for final year bachelor students, nor for people working in industry who have received only basic courses in classical mechanics, electromagnetism, quantum mechanics, chemistry and materials science. The challenge of this book is to give an introduction to Mössbauer Spectroscopy for this level. The ultimate goal of this book is to give this audience not only a scientific introduction to the technique, but also to demonstrate in an attractive way the power of Mössbauer Spectroscopy in many fields of science, in order to create interest among the readers in joining the community of Mössbauer spectroscopists. This is particularly important at times where in many Mössbauer laboratories succession is at stake. This book will be used as a textbook for the tutorial sessions, organized at the occasion of the 2011 International Conference on the Application of Mössbauer Spectroscopy (ICAME2011) in Tokyo.

Mössbauer Effect: Principles and Applications focuses on the processes, methodologies, and reactions involved in Mössbauer effect, as well as atomic motion, use of the effect in studying hyperfine structures, quadropole coupling, and isomer shift. The manuscript first discusses resonant absorption, emission of gamma rays by nuclei, width of gamma-ray spectrum, and emission from bound atoms. The text then surveys counting, modulation, and low-temperature techniques. The publication offers information on relativity and the Mössbauer effect, atomic motion, quadropole coupling, and magnetic hyperfine structure. Discussions focus on gravitational red shift and combined magnetic and electric hyperfine coupling. The text then evaluates magnetism of metals and alloys, chemical applications, and linewidth and line shape. The manuscript is a valuable source of data for physicists and readers interested in the Mössbauer effect.

Rudolph Mossbauer discovered the phenomenon of recoil-free nuclear resonance fluorescence in 1957-58 and the first indications of hyperfine interactions in a chemical compound were obtained by Kistner and Sunyar in 1960. From these beginnings the technique of Mossbauer spectroscopy rapidly emerged and the astonishing versatility of this new technique soon led to its extensive application to a wide variety of chemical and solid-state problems. This book reviews the results obtained by Mossbauer spectroscopy during the past ten years in the belief that this will provide a firm basis for the continued development and application of the technique to new problems in the future. It has been our aim to write a unified and consistent treatment which firstly presents the basic principles underlying the phenomena involved, then outlines the experimental techniques used, and finally summarises the wealth of experimental and theoretical results which have been obtained. We have tried to give some feeling for the physical basis of the Mossbauer effect with out extensive use of mathematical formalism, and some appreciation of the experimental methods employed without embarking on a detailed discussion of electronics and instrumentation. However, full references to the original literature are provided and particular points can readily be pursued in more detail if required.

This up-to-date review closes an important gap in the literature by providing a comprehensive description of the Mössbauer effect in lattice dynamics, along with a collection of applications in metals, alloys, amorphous solids, molecular crystals, thin films, and nanocrystals. It is the first to systematically compare Mössbauer spectroscopy using synchrotron radiation to conventional Mössbauer spectroscopy, discussing in detail its advantages and capabilities, backed by the latest theoretical developments and experimental examples. Intended as a self-contained volume that may be used as a complete reference or textbook, it adopts new pedagogical approaches with several non-traditional and refreshing theoretical expositions, while all quantitative relations are derived with the necessary details so as to be easily followed by the reader. Two entire chapters are devoted to the study of the dynamics of impurity atoms in solids, while a thorough description of the Mannheim model as a theoretical method is presented and its predictions compared to experimental results. Finally, an in-depth analysis of absorption of Mössbauer radiation is presented, based on recent research by one of the authors, resulting in an exact expression of fractional absorption, otherwise unavailable in the literature. The whole is supplemented by elaborate appendices containing constants and parameters.

This is the tenth volume of a continuing series intended to provide a forum for publication of develop ments in f:lossbauer Effect t1ethodology and in Spectroscopy and its applications. r~ossbauer Effect t·1ethodo 1 ogy, Vo 1 ume 1 0, records the proceedings of the Tenth Symposium on r10ssbauer Effect Hethodo 1 ogy. The Sympos i urn \'laS sponsored by the Ne~" England Nuclear Corporation, with special emphasis on applications in catalysis and in biology. The Symposium VIaS held in the t, lercury Ballroom of the New York Hilton on February 1, 1976. Dr. f,1. Good presided over the meeting. 11ore than one hundred participants were involved in the technical sessions and the exhibit of H5ssbauer effect instruments, equipment and materials by Elscint, Inc., Ranger Engineering and New England Nuclear. Continued evolution and improvement was the keynote of the ex hi bi to As has been our experience in recent Symposia, many more papers were submitted than could be accommodated. The Selection Committee was hard-pressed to limit the number of papers, and the sessions were lengthy, despite their efforts.

This is the sixth volume of a series that provides a continuing forum for publication of developments in M6ssbauer effect method ology and of spectroscopy and its applications. M ossbauer Effect Methodology, Volume 6, records the proceedings of the Sixth Symposium on M6ssbauer Effect Methodology. The symposium was sponsored by the New England Nuclear Corporation and concentrated on methodology, applications, and spectroscopy, with special sections on lunar sample work and on standardization and nomenclature. The symposium was held at the Palmer House in Chicago on January 25, 1970. Dr. J. C. Walker presided over the after noon and evening sessions. About two hundred participants attended, reflecting the continued importance of and interest in this series. Austin Science Associates, Elron Electronic Industries, High Voltage Engineering Corporation, and Reuter-Stokes Electronic Components Company demonstrated lines of equipment for M6ssbauer work. The usual high degree of interest in the well-designed commercial instrumentation was evident. The highlight of the symposium was the session on lunar samples. Fortuitously, the timing of the symposium permitted it to provide one ofthe earliest exposures ofthe lunar results to the scientific community. Many papers on other applications were presented, including work on frozen aqueous solutions. Four papers on methodology development made up one session, including reports on a polarized source, on a coincidence technique, and on the use of radio frequency to perturb hyperfine levels. As usual, many of the papers report work in fields remote from basic physics.
