Abstract

We study nuclear responses to low-energy neutrinos through the neutral Gamow- Teller strength B(GT0). As a concrete example we adopt the 56Fe isotope which plays important role in core collapse supernova. By using the quasi-particle RPA method we found that this strength is mainly concentrated on the resonance at around ~10 MeV. Within the QRPA, we may also examine the changes in B(GT0) induced by non-zero values of the momentum transfer in astrophysical neutrino scattering on nuclei.
