Cross sections for neutral-current neutrino scattering on ²⁰⁸Pb

We present continuum random phase approximation (CRPA) calculations for neutral-current neutrino scattering off ²⁰⁸Pb. These reactions are of interest for the terrestrial detection of supernova neutrinos. We fold the computed cross sections with a Fermi-Dirac distribution to obtain information about these processes and examine the dependence of the response on the spectrum parameters. The experimental interest in neutron knockout induced by neutrino interactions on ²⁰⁸Pb motivated an analysis of the CRPA branching ratios and single-particle knockout channels. We investigate the role of the single-particle wave functions and the residual interaction for the response. We compare our cross sections with previous work.
