A neutron-energy dependent angular distribution was measured for individual $\gamma$-rays from the 3.2 eV $p$-wave resonance of $^{131}$Xe+$n$, that shows enhanced parity violation owing to a mixing between $s$- and amplitudes. The $\gamma$-ray transitions were identified, with respect neutron momentum evaluated as function energy 7132 keV $\gamma$-rays, which correspond transition 1807 excited state $^{132}$Xe. is considered originate interference amplitudes, will provide basis quantitative understanding enhancement mechanism fundamental in compound nuclei.
