Abstract

Work done between September 1, 1978, and September 1, 1979, involved the study of low-energy and relativistic heavy-ion reactions. In the former area most of the effort went into a careful re-examination of the failure to synthesize superheavy elements in complete fusion reactions. It was concluded that fission barriers are of the order of 5 or 6 MeV corresponding to a half-life of 10/sup 5/ years, a value precluding their occurrence in nature. In the area of relativistic heavy-ion (RHI) reaction studies, the most interesting results came in studies of the energy dependence of the product mass and charge distributions resulting from the interaction of RHIs with U and studies of the recoil properties of the target residues produced in the reaction of RHIs with heavy targets. Lists of personnel, publications, and oral presentations are included, along with a collection of reprints and preprints. Eight of the individual articles in this report are indexed separately.
