Abstract: Neutrino-induced reactions on
56
Fe and
56
Ni are investigated based on a new shell-model Hamiltonian for
pf
shell. The calculated charged current reaction cross section on
56
Fe induced by decay-at-rest (DAR) neutrinos
is shown to be consistent with the observation. The Gamow-Teller strength in
56
Ni is found to be more spread
compared to previous calculations and result in a considerably large branching ratio for the proton knock-out
channel. As a consequence of this, the production yields of heavy elements such as
55
Mn in population III stars
are shown to be enhanced for the new Hamiltonian.
