Study of analogue states in ⁵²Cr through proton capture by ⁵¹V

Abstract

γ-Ray yield function has been studied for the proton capture by vanadium in the proton energy range 720-1300 keV. Isobaric analogues of low lying states in ⁵²V have been identified. At two resonances the γ-decay and γ-ray angular distributions have been obtained and the branching ratios and the multipole mixing ratios have been deduced. The analogue-antianalogue M1 transition in ⁵²Cr is found to be strongly hindered as in other f_7/2 nuclei. The Q-value obtained for this reaction is (10500±2.8) keV and the Coulomb displacement energy is (8.06±0.01) MeV. An upper limit of 2 meV has been obtained for thea- decay strength of the 11.395 MeV state in ⁵²Cr.
