宇称非守恒冷中子-仲氢相互作用

Parity nonconserving cold neutron-parahydrogen interactions

T. M. Partanen

摘要:

计算了冷中子与仲氢宇称非守恒相互作用的三个π主导观测量。考虑了横向极化中子自旋旋转、非极化中子纵向极化和辐射极化中子俘获的光子不对称性。对于观测值的数值计算,Reid 93势考虑了强相互作用,DDH模型考虑了宇称非守恒相互作用和2 π交换.

英文摘要:

Three pion dominated observables of the parity nonconserving interactions between the cold neutrons and parahydrogen are calculated. The transversely polarized neutron spin rotation, unpolarized neutron longitudinal polarization, and photon-asymmetry of the radiative polarized neutron capture are considered. For the numerical evaluation of the observables, the strong interactions are taken into account by the Reid93 potential and the parity nonconserving interactions by the DDH model along with the two-pion exchange.
