Gamow-Teller transitions to ⁹³Zr via the ⁹³Nb (t, ³He + γ) reaction at 115 MeV/u and its application to the stellar electron-capture rates

NUCLEAR REACTIONS ⁹³Nb(t, ³He), E=115 MeV/nucleon; measured ³He particle spectra, Eγ, double-differential σ(θ) using S800 spectrograph and GRETINA array at NSCL-MSU Coupled Cyclotron Facility. ⁹³Zr; deduced levels, L-transfer, J, π, B(GT), electron capture (EC) rates in the late evolution of core-collapse supernovae, DWBA and multipole decomposition analysis (MDA). Comparison with QRPA and shell-model calculations.
