It is shown that, by introducing a resonance phase for two opposite-parity
quasistationary states of the same spin, the observed sign dependence of P-
odd effects in neutron-induced reactions can be matched with theoretical pr
edictions. The proposed approach makes it possible to deduce information ab
out the isospin structure of weak nucleon-nucleon interaction. (C) 2001 MAI
