Vv. Flambaum et Vg. Zelevinsky, POSSIBLE DOUBLET MECHANISM FOR A REGULAR COMPONENT OF PARITY VIOLATION IN NEUTRON-SCATTERING, Physics letters. Section B, 350(1), 1995, pp. 8-12
A nucleus with octupole deformation of the mean field reveals rotation
al doublets with the same angular momentum and opposite parity. Mediat
ed by the Coriolis-type interaction, the doublet structure leads to a
strong regular component in the parity violation caused by weak intera
ction. This can explain sign correlations observed in polarized neutro
n scattering by Th-232.
