RESONANCES IN THE S32, 33, 34 (P, GAMMA) CL33, 34, 35 REACTIONS WITH BOMBARDING ENERGIES IN THE ONE MEV TO TWO MEV RANGE.
Abstract
A search for resonances in the S32, 33, 34 (p. gamma) Cl33, 34, 35 reactions for proton energies in the one to two MeV range was conducted. Natural sulfur targets, in elemental form with a thin gold overlay, with thicknesses about 5 keV for 1.5 MeV protons, and enriched S33 and S34 targets, in Ag2S compound form, with thicknesses about 1-2 keV for 1.5 MeV protons, were used. Gamma rays were detected at 55 degrees relative to the protonbeam direction. In each of the three yield curves, pulses were counted simultaneously with three scalers biased for selected gamma-ray energies. Approximately thirty S34 resonances were found in the energy region studied. Most of the observed resonance widths were less than or equal to 2 keV. In the S33 yield curve, twelve prominent resonances, with widths less than or equal to 2 keV, were observed in addition to others previously known. Above 1600 keV, evidence for many weak, closely-spaced S33 resonances was found. (Author)
