The International Conference on Spectroscopy of Heavy Nuclei was held in Agia Pelagia on the Greek island of Crete from 25 June to 1 July 1989. This volume contains 45 papers, both invited and contributed. The conference provided a forum for the presentation and discussion of the most recent data and theory available over a wide range of topics. That so many ideas were forthcoming clearly shows the dynamic state of nuclear structure physics. This is emphasized by the challenge to existing theory by the latest experimental results and vice versa. These proceedings will be of great value to researchers in nuclear structure as they represent the latest developments from the major practitioners in this field.
