Two-body effects and deuteron photodisintegration with polarized and unpolarized gamma rays

Employing the two-body charge effects owing to $\pi$ exchange and the current effects owing to $\pi$-, $\rho$-, and $\omega$-exchange processes, the angular distribution, asymmetry function, and polarization of nucleons from the ${}_{}{}^2{}_{}{}^{}\mathrm{H}{(\gamma ,n)}^1\mathrm{H}$ reaction are investigated. The cross section and polarization parameters are reported for the Paris, Yale, super-soft-core B, and Hamada-Johnston potentials. The changes in the parameters owing to exchange effects are found to be nearly the same for all the potentials, and all the potentials are found to reproduce the low energy angular distribution data provided a suitable normalization factor is chosen.
