Technical progress report and proposal for continuation of contract

A considerable amount of experimental work was done on the importance of two-step mechanisms in nuclear reactions. The medium-energy experimental group participated in construction of the EPICS facility at LAMPF. The theoretical program concentrated on investigations of $pi$--nucleus interactions and finite- range effects. The report is arranged as follows: experimental program (nuclear physics, intermediate energy physics, apparatus and facility development, cyclotron operation, outside users of cyclotron facilities), theoretical program, publications and reports, and personnel. The nuclear physics section of the report contains work on charged-particle experiments (single-nucleon-transfer reactions, multinucleon-transfer reactions, charge-exchange reactions, elastic and inelastic scattering, charged-particle reaction studies on $sup 14$C), gamma- ray experiments and beta decay, neutron time-of-flight experiments, x-ray fluorescence trace element analysis, and other activities. Seventeen items with significant amounts of data are listed separately by title. (RWR
