The 30Si(þ, γ) 31P reaction for bombarding energies between 1.53 and 2.00 MeV

Abstract

Eighteen resonances have been observed in the 30Si(þ, γ) 31P reaction with protons in the energy region E p = 1.53–2.00 MeV. The resonance energies, the resonance strengths, the excitation energies and the decay modes of the corresponding levels in 31P are reported. The total widths of a few resonance levels as obtained from yield measurement with a very thin target are compared with the results of elastic proton scattering. The spin of all resonance levels has uniquely been determined from gammaray angular distribution and/or gamma-gamma angular correlation measurements. In some cases, a parity assignment has been obtained from 1) the evaluation of the M2 strength of the de-excitation radiation, 2) the calculation of the reduced proton width, and/or 3) the interpretation of recent 30Si(þ, þ) 30Si work.
