    the gamow-teller strength distribution function, b(gt), for the odd z parent 51v, n−z=5, up to 30 mev of excitation energy in the daughter 51ti is calculated in the domain of proton-neutron quasiparticle random phase approximation (pn-qrpa) theory. the pn-qrpa results are compared against other theoretical calculations, (n, p) and high resolution (d, 2he) reaction experiments. for the case of (d, 2he) reaction the calibration was performed for 0≤e j ≤5.0 mev, where the authors stressed that within this excitation energy range the δl=0 transition strength can be extracted with high accuracy for 51v. within this energy range the current pn-qrpa total b(gt) strength 0.79 is in good agreement with the (d, 2he) experiment’s total strength of 0.9±0.1. the pn-qrpa calculated gamow-teller centroid at 4.20 mev in daughter 51ti is also in good agreement with high resolution (d, 2he) experiment which placed the gamow-teller centroid at 4.1±0.4 mev in daughter 51ti. the low energy detailed gamow-teller structure and gamow-teller centroid play a sumptuous role in associated weak decay rates and consequently affect the stellar dynamics. the stellar weak rates are sensitive to the location and structure of these low-lying states in daughter 51ti. the calculated electron capture rates on 51v in stellar matter are also in good agreement with the large scale shell model rates.
