  Resonant capture of antineutrinos can be accomplished by exploiting the
monoenergetic antineutrinos emitted in bound state beta-decay. Extending this
idea, I explore conditions for recoilless resonant capture in the system 3H -
3He. Observation of such transitions can set the stage for placing stringent
limits on the neutrino parameter theta-13 on an ultra-short baseline of ~9 m
and for observing the gravitational red shift of neutrinos
