The gallium solar neutrino capture cross section revisited by W.C. Haxton, Evan Rule

“…The constraints depend on the neutrino absorption cross sections for various solar sources. Following recent work updating the 51Cr and 37Ar neutrino source cross sections, we reevaluate the 71Ga solar neutrino cross sections, focusing on contributions from transitions to 71Ge excited states, but also revising the ground-state transition to take into account new 71Ge electron-capture lifetime measurements and various theory corrections. …”
