Abstract
The cross sections of charged- and neutral-current neutrino-induced reactio ns on the iron isotopes Fe52-60 are evaluated with various supernova neutri no spectra. The Gamow-Teller-like contributions to the cross sections are c alculated using the large-scale shell-model calculations, and the resulting strength distributions corresponding to the operator sigmat(0) are present ed. The transitions for other multipoles are based on the random phase appr oximation. Partial cross sections for decay into neutron, proton and gamma channels are obtained by folding the neutrino excitation spectra with branc hing probabilities derived from a statistical model.
