Printed in Singapore by Uto-Print V PREFACE Succeeding to the first symposium in 1991, the Tours Symposium on Nuclear Physics II was held in Tours from August 30 to September 2,1994. The Symposium, an international scientific project of Konan University, was organized in collaboration with SUBATECH (Laboratoire de Physique Subatomique et des Technologies Assoctees), Nantes. This project was promoted by the cooperative relationship between Konan University and the Conseil GteneVal de Touraine which has been strengthened in 1993 by Mr. Morimasa Ogawa (Trustee of Konan University), Dr. Kazunori Yuasa (former President of Konan University) and Dr. Jean Kelaneau (President of the Conseil G6n6ral de Touraine). The main frame of the symposium was structured by the organizing committee held in Paris in September, 1993, resulting in the selection of the five topics. . nuclear astrophysics (NAP) . physics with exotic nuclei (PEN) . heavy ion collisions (HIC) . very heavy elements (VHE) . spin-isospin excitation (SIE) Invited papers were selected through contributions as well as recommendations by the committee members. In this respect, we thank Dr. Miinzenberg (GSI, Darmstadt), Dr. C. Signorini (INFN, Padova), Dr. J.P. Coffin (CRN, Strasbourg), Dr. J. Galin (GANIL, Caen), Dr. D. Ardouin (SUBATECH) and others for their sense of responsability and the quality of selection. As a result, the symposium was full of new results and rich perspectives. This volume includes 47 articles on invited talks along with 9 summaries by chairpersons. The summaries also help clarify the scientific goals of the individual fields. We would like to express sincere appreciation to all the participants, speakers, and chairpersons who led this symposium to a success. We are grateful to : - Marie-Luce Seguin (SUBATECH), a local secretary, for hard work on the administrative jobs, - Monique Bex, Solange Geswend (GANIL) for collecting and assembling manuscripts, - Catherine Geneste (Comite* d'Expansion Economique de Touraine) for setting up the reception party at Chateau d'Artigny, - Creola Miki (Lycee-College Konan de Touraine) for her local support, and - Claude Vivian and Isabelle Renon (Hotel Univers) for offering friendly atmosphere and good services for the symposium. Special thanks go to Y. Aritomo, K. Ishikawa, H. Mabuchi, H. Owada, K. Tamakoshi, and T. Tokuda, students of Konan University, for their assistance during the symposium. Finally it was our great honor to receive financial support from GANIL (Grand Accelerateur National d'lons Lourds, Caen) and the Conseil G6n6ral d'Indre et Loire, and academic support from GANIL and RCNP (Research Center for Nuclear Physics, Osaka University). With all the best efforts by the colleagues and friends, the symposium was, after all, full of life.

I am also sure that the Symposium resulted in fruitful discussions and a remarkable development more than expected in many parts. I express many thanks to Nantes University for his cooperation, and to the Assembly of Loire Prefecture and Ganil Research Institute for their fina ncial support. It was my great honor to have met Dr. J.Delaneau, Council General of Loire Prefecture, Mr. Briand, Manager of Saint Cyr, Dr. H.Mouray, President of University of Tours, Madame Lespagnol, Principal of College of Bechellerie, Mr. T.Akita, Principal of Lycee-College Konan de Touraine and many important people at the Reception Party held in Chateau D'Artigny. My pleasure is to have confirmed through this symposium the fact that the friendship among scholars and researchers was more deepened, and accordingly led to a further development of friendly relations not only between Tours and Konan in Kobe, but also France and Japan. When we visited Mr. P.Briand, at his desk, he proposed a new plan of interchange of young people between St. Cyr-sur-Loire and Kobe, where they will be able to stay at each host family, so that the mutual understanding will be more deepened through this program. We are agreeable with his proposal. Touraine area, where Lycee-College Konan is located, is a wonderful and beautiful city having old castles, antique shops, small hotels and green hill countries. It has been called as a " Beautiful Garden of France " , where we enjoyed our first visiting. The famous castle " Cande " must become a cheerful place when our student groups of Konan University will use it for their seminar's room in the future. I hope, the planning of the third Tours Symposium will be realized by the faculty groups of literature and social sciences in the near future.
