Gamma Radiation from Proton Capture inNa23

Abstract

The $\gamma$-ray decays of twelve resonances in the reaction ${\mathrm{Na}}^{23}(p, \gamma ){\mathrm{Mg}}^{24}$ in the proton energy range from 0.58 to 1.42 Mev have been re-examined with large scintillation detectors and coincidence techniques. A number of weaker cascades through the states of ${\mathrm{Mg}}^{24}$ between the excitation energies of 6 Mev and 8 Mev has been found. Relative intensities have been measured for the observed $\gamma$ rays and consistent decay schemes proposed. The absolute yields of this reaction at these resonances have been determined.
