Neutrino spectrum and energy loss rates due to weak processes on hot Fe in pre-supernova environment
Alan A. Dzhioev, A. V. Yudin, N. V. Dunina-Barkovskaya +1
Applying TQRPA calculations of Gamow--Teller strength functions in hot nuclei, we compute the (anti)neutrino spectra and energy loss rates arising from weak processes on hot $^{56}…
