First Constraint on P-odd/T-odd Cross Section in Polarized Neutron Transmission through Transversely Polarized $^{139}$ La

Rintaro Nakabe, Clayton J. Auton, Shunsuke Endo +27

We report the first constraint on time-reversal invariance violating (TRIV) effects in polarized neutron transmission through a transversely polarized $^{139}$ La target. We formula…

Angular distribution of $γ$ -rays from a neutron-induced $p$ -wave resonance of $^{132}$ Xe

T. Okudaira, Y. Tani, S. Endo +16

A neutron-energy dependent angular distribution was measured for individual $γ$ -rays from the 3.2 eV $p$ -wave resonance of $^{131}$ Xe+ $n$ , that shows enhanced parity violation owin…

Measurement of the transverse asymmetry of $γ$ -rays in the $^{117}$ Sn(n, $γ$ ) $^{118}$ Sn reaction

S. Endo, T. Okudaira, R. Abe +13

Largely enhanced parity-violating effects observed in compound resonances induced by epithermal neutrons are currently attributed to the mixing of parity-unfavored partial amplitud…
