Query: Low-Energy Inelastic Neutrino Reactions on 4He   The inelastic scattering of neutrino off 4He is calculated microscopically at
energies typical for core collapse supernova environment. The calculation is
carried out with the Argonne V18 nucleon--nucleon potential and the Urbana IX
three nucleon force. Full final state interaction is included via the Lorentz
integral transform (LIT) method. The contribution of axial meson exchange
currents to the cross sections is taken into account from effective field
theory of nucleons and pions to order O(Q^3).
