摘要: Abstract Angular distributions have been measured for six 36 Ar(p, γ ) 37 K resonances in the E p = 0.9−3.0 MeV energy region. These experiments yield spin- and parity assignments to seven excited states of K, γ-ray branching ratios each state, together with multipolarity mixing most transitions. Lifetimes deduced from same data DSA method. Excitation energies determined a precision up 20 eV. A resonance- excitation-energy measurement at 918keV resonance yields Q -value 1857.57 ± 0.09 keV. The 1 curve, 2.6–3.3 region, additional information on excitation typical 0.6 new levels allow detailed comparison level schemes mirror nuclei Ar K. present experimental agree quite well results previous shell-model calculations.
