Abstract

In this work, we explore
the role of deformation parameter (β) on the calculated Gamow-Teller (GT)
strength distributions and electron capture cross-sections (ECC) for ^46,48,50Cr
isotopes within the formalism of the proton neutron-quasi-particle random phase
approximation (pn-QRPA). Three different β parameters were used in the present
study. Two of them were calculated by using the interacting boson model (IBM)
and the macroscopic-microscopic (Mac-mic) models. The third one is the
experimental β values obtained by employing its relation with the experimental
B(E2)↑ values. The GT strength distributions were
widely dispersed among all the daughter states of the given isotopes. They were
found to have an inverse relation with the β
parameter i.e decreasing with increasing the β value. The ECC was
computed as a function of the β parameter and the results suggest that the
calculated ECC decreased with decreasing value of the β for the selected cases.
