ACTA POLYTECHNICA SCANDIANAVICA PHYSICS INCLUDING NUCLEONICS SERIES No. 29 An Investigation of the K39(p,γ)Ca40 Reaction at Proton Energies 1103KeV, 1103KeV and 1153 Kev

摘要

A study has been made of the gamma ray spectra of the resonances at proton energies 1103 keV, 1131 keV and 1153 keV in the K39(p, γ)Ca40 reaction, and the main decay features are given. We have found evidence to supporting the existence of a new Ca40 level, with an energy at about 4.70 MeV. Measurement was made of the angular distribution of the 9.44 MeV gamma ray de-exciting the 1131 keV resonance level. The spin and parity of this resonance level is probably 1+ or 1-.
