N2 - We investigate nucleosynthesis in the supernova post-core bounce neutrino-driven wind environment in the presence of active-sterile neutrino transformation. We consider active-sterile neutrino oscillations for a range of mixing parameters: vacuum mass-squared differences of 0. 1eV2≤δm2≤100eV2, and vacuum mixing angles of sin 22θv≥10-4. We find a consistent r-process pattern for a large range of mixing parameters that is in rough agreement with the halo star CS 22892-052 abundances and the pattern shape is determined by fission cycling. We find that the allowed region for the formation of the r-process peaks overlaps the liquid scintillator neutron detector (LSND) and null-short baseline (NSBL) (3+1) allowed region.
