|Title:||Parity violation in deuteron photo-disintegration and intence MeV photons.|
|Abstract:||We analyze the energy dependence for two types of parity-non-conserving (PNC) asymmetries in the reaction, gamma D to np, in the near-threshold region. The first one is the asymmetry in reaction with circularly polarized photon beam and unpolarized deuteron target. The second one corresponds to those with an unpolarized photon beam and polarized target. We find that the two asymmetries have quite different energy dependence and their shapes are sensitive to the PNC-meson exchange coupling constants.
The predictions to provide definite constraints for the PNC-coupling constants for the future possible experiments are discussed.
