ELECTRONUCLEAR RESEARCH DIVISION ANNUAL PROGRESS REPORT FOR PERIOD ENDING JANUARY 16, 1961

Research with 28-Mev N/sup 3+/ ions from the ORNL 63-Inch Cyclotron included studies of elastic and inelastic scattering, of angular distributions from transfer reactions, and of nuclear reactions resulting in the evaporation of alpha particles and protons. The research program associated with the 22-Mev protons from the ORNL 86-Inch Dyclotron lncluded studies of bound states of neutrons, the investigation of energy levels in neutron-deficient rareearth nuclei, and the production of neutron-deficient radiolsotopes. Theoretical studies are belng made for the interpretation of both proton-induced and nitrogen- induced reactions with distorted-wave Born approximatlon calculations and with the optical model. Fabrication and assembly of Cyclotron Analogue II are nearing completion. The building for the Oak Ridge lsochronous Cyclotron was completed. The final design work is well advanced; the major heavy components were fabricated and are being installed. (For preceding period see ORNL-3047.) (auth
