Energy Levels in Sulfur Nuclei

A study has been made of the proton groups from the reaction of 3.22-Mev deuterons with sulfur in the form, primarily, of ${\mathrm{H}}_2$S gas. The following $Q$ values have been assigned to the reaction ${\mathrm{S}}^{32}\mathrm{}\left(\mathrm{dp}\right)\mathrm{}{\mathrm{S}}^{33}:6.48, 5.69, 4.58, 4.31, 3.63, 3.33, 2.60, 2.33, 2.06, 1.78, 1.37, 0.85, \mathrm{and} 0.18$ Mev, corresponding to the ground state and twelve excited states of ${\mathrm{S}}^{33}$. Four of these groups have been investigated for proton gamma-ray coincidences to confirm this assignment. The yield as a function of deuteron energy has been observed for the six highest energy groups and indication of the presence of some broad resonances found. A qualitative measurement of the variation with angle of relative yields of the groups has indicated a proton intensity distribution that is symmetric for some groups and asymmetric for others. The cross section for the reaction for 90° observation has been found to be 1.2 barns. The mass difference ${\mathrm{S}}^{33}$-${\mathrm{S}}^{32}$ has been calculated to be 0.99963 mass unit.
