We reexamine the conditions under which the resonant-exchange mechanism proposed by Watson can be expected to lead to a first-order rate for the neutrino-mediated transmutation of H3 and He3 atoms into each other. In the course of this, we are able to formulate rather general criteria for when such ''fragile'' first-order resonance rates, in fact, deteriorate into more familiar second-order ones.
