  Beta decay and electron capture on isotopes of chromium are advocated to play
a key role in the stellar evolution process. In this paper we endeavor to study
charge-changing transitions for 24 isotopes of chromium ($^{42-65}$Cr). These
include neutron-rich and neutron-deficient isotopes of chromium. Three
different models from the QRPA genre, namely the pn-QRPA, the Pyatov method
(PM) and the Schematic model (SM), were selected to calculate and study the
Gamow-Teller (GT) transitions in chromium isotopes. The SM was employed
separately in the particle-particle ($pp$) and $pp$ + particle-hole ($ph$)
channels. To study the effect of deformation, the SM was first used assuming
the nuclei to be spherical and later to be deformed. The PM was used both in
$pp$ and $pp$ + $ph$ channels but only for the case of spherical nuclei. The
pn-QRPA calculation was done by considering both $pp$ and $ph$ forces and
taking deformation of nucleus into consideration. A recent study proved this
version of pn-QRPA to be the best for calculation of GT strength distributions
amongst the QRPA models. The pn-QRPA model calculated GT distributions had
low-lying centroids and small widths as compared to other QRPA models. Our
calculation results were also compared with other theoretical models and
measurements wherever available. Our results are in decent agreement with
previous measurements and shell model calculations.
