Possible doublet mechanism for a regular component of parity violation in neutron scattering

Abstract

A nucleus with octupole deformation of the mean field reveals rotational doublets with the same angular momentum and opposite parity. Mediated by the Coriolis-type interaction, the doublet structure leads to a strong regular component in the parity violation caused by weak interaction. This can explain sign correlations observed in polarized neutron scattering by ${}^{232}$Th.
