This volume contains the proceedings of a workshop held at Drexel University from September 1 to September 3, 1980, under the joint auspices of Drexel University, The University of Tennessee and Vanderbilt University. The workshop dealt with subjects of topical importance to the nuclear physics community: high spin phenomena, heavy ion reactions, transfer reactions, microscopic theories of nuclear structure and the interacting boson model, and miscellaneous topics. This pro ceedings contains all of the invited papers plus short manuscripts expanding on the materials of the invited papers. A total of about 85 participants came to the workshop. The format of the conference was kept informal on purpose, so as to facilitate the discussions. Unfortunately, these discussions, at times intense, could not be included in this volume due to the lack of secretarial help during the meeting. A great deal of current information was exchanged during the conference. However, the full impact of a conference can only be realized when the proceedings have been published and read by par ticipants as well as other colleagues in this field of physics who were not in attendance. We sincerely hope that these proceedings will be useful in this regard.
