Competition of deformation and neutron-proton pairing in Gamow-Teller transitions for ${}^{56,58}$Ni and ${}^{62,64}$Ni

Eunja Ha, Myung-Ki Cheoun

We investigated effects of neutron-proton ($np$) pairing correlations comprising isoscalar (IS) and isovector (IV) component on Gamow-Teller (GT) transitions of ${}^{56,58,62,64}$Ni…
