We discuss how matter-enhanced active-sterile neutrino transformation in the [Formula Presented] and [Formula Presented] channels could enable the production of the rapid neutron capture [Formula Presented]-process) nuclei in neutrino-heated supernova ejecta. In this scheme the lightest sterile neutrino would be heavier than the [Formula Presented] and split from it by a vacuum mass-squared difference of [Formula Presented] with vacuum mixing angle [Formula Presented] © 1999 The American Physical Society.
