Abstract :In this work, we explore the role of deformation parameter insert ignore into journalissuearticles values(β); on the calculated Gamow-Teller insert ignore into journalissuearticles values(GT); strength distributions and electron capture cross-sections insert ignore into journalissuearticles values(ECC); for 46,48,50 Cr isotopes within the formalism of the proton neutron-quasi-particle random phase approximation insert ignore into journalissuearticles values(pn-QRPA);. Three different β parameters were used in the present study. Two of them were calculated by using the interacting boson model insert ignore into journalissuearticles values(IBM); and the macroscopic-microscopic insert ignore into journalissuearticles values(Mac-mic); models. The third one is the experimental β values obtained by employing its relation with the experimental Binsert ignore into journalissuearticles values(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.
