First Constraint on P-odd/T-odd Cross Section in Polarized Neutron Transmission through Transversely Polarized 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 La target. We formula…

Measurement of the transverse asymmetry of -rays in the Sn(n,)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…
