Gamma rays from ²³Na states excited in the ¹²C(¹²C, p) reaction at E = 38.6 MeV

Abstract

The ${}^{12}\text{C}\text{(}{}^{12}\text{C, p}\text{γ)}{}^{23}\text{Na}$ reaction was studied at a c.m. bombarding energy of 19.3 MeV. At this energy the excitation functions for the proton groups to the 9.04 MeV and 9.81 MeV ²³Na states exhibit a strong resonance. The γ-decay of the 9.04 and 9.81 MeV levels was recorded and found to be consistent with the two states being the $\text{15}\text{2}{}^{\mathrm{+}}$ and $\text{17}\text{2}{}^{\mathrm{+}}$ members, respectively, of the ²³Na ground-state rotational band. Other nearby spin values cannot be excluded.
