Properties of the Excited States ofNa22from theNe21(p, γ)Reaction

Abstract

Proton capture resonances in ${\mathrm{Ne}}^{21}$ have been observed at 775 kev, 865 kev, 1010 kev, 1120 kev, 1215 kev, 1296 kev, and 1354 kev for proton bombarding energies ranging between 600 kev and 1500 kev. Pulse-height spectra of the resultant gamma radiation are presented for the two lowest resonances. At the 776-kev resonance the transitions are predominantly to the ground state, whereas the 865-kev resonance seems to decay mainly to the 2.25-Mev state. Arguments are presented showing that this is consistent with identifying this level as the second $T=1\mathrm{}$, $J=2^{+}$ state in ${\mathrm{Na}}^{22}$.
