$P$-odd effects observed in neutron-induced reactions and isospin structure of weak nucleon-nucleon interaction

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 predictions. The proposed approach makes it possible to deduce information about the isospin structure of weak nucleon-nucleon interaction.
