Radiation widths of resonances in the 40Ar(pγ)41K reaction
The excitation function for the 40Ar(pγ)41K reaction at the accelerated proton energy Ep= 450–2700 keV is studied. Positions of 168 resonances identified as levels of the 41K nucleus are observed in this energy range. The data for the proton energy Ep < 1 MeV and Ep > 2 MeV are obtained for the first time. Relative yields of γ rays observed in the decay of the resonances are calculated from a comparison with the yield of the calibrating resonance at Ep= 1102 keV. Total radiation widths of the resonances are calculated on the basis of the data obtained.
