Abstract : The report describes the research program done at the NRL Sector-Focusing Cyclotron during the year 1972. The basic research program is devoted primarily to problems involving nucleon systems and light nuclei. Experimental results of deuteron breakup by protons are compared with exact calculations, and it is concluded that the calculations are not yet using the proper nuclear potential. The problem of deuteron breakup by deuterons has been investigated with the conclusion that it is not necessary to invoke a singlet final state interaction to explain observed spectra. The neutron radiotherapy project in the applications research program is investigating the efficacy of neutrons in the treatment of cancer. A number of measurements have been performed, including neutron dose rate, neutron energy spectra, depth doses for various collimators, oxygen enhancement ratios, and radiobiological effectiveness of this beam using various biological systems.
