  An active two-neutrino state's coupling to an intermediate scalar meson, and
thence to a two-antineutrino state, is one idea for catalyzing transitions from
active to sterile neutrinos, in an implementation of the Dodelson-Widrow
proposal for the production of sterile and somewhat massive neutrinos as dark
matter candidates. We propose some mechanics that promises to use the very same
model with the same mass and coupling parameters, in order to achieve similar
results, but orders of magnitude faster; or alternatively, similar results but
beginning with vastly reduced coupling constants. The model then would become
much less constrained by consistency with laboratory and astrophysical data.
