Abstract

Proton energies and strengths of 17 resonances in the 22Ne(p,γ)23Na reaction were determined for Ep < 1.1 MeV. A new resonance was observed at Ep = 630.5 ± 1.0 keV. The γ-decay of 17 resonances was studied by means of a 40 cm3 Ge(Li) detector. The excitation energies and branching ratios of 36 bound levels were determined. A new level was observed at Ex = 8299 ± 3 keV. The lifetimes of the ten Ex = 2.08–4.77 MeV levels were determined with the Doppler-shift attenuation method. The spins of the Ep = 725 and 928 keV resonances were determined from angular distribution measurements. Both have J = 32.
