Photodisintegration cross sections of the deuteron

Abstract

Employing a variety of local static potentials, the bremsstrahlung-weighted and integrated cross sections for the photodisintegration of the deuteron are calculated. The effect of variation of the tensor force in the two-nucleon Yale potential in a manner as to affect only the D state probability of the deuteron, while leaving the values of the other two-body observables unchanged, is studied. It is found that though the contribution of the central, tensor, and spin–orbit components of the two-nucleon potentials to the integrated cross section may vary significantly, the integrated cross section does not change by more than a few percent. The sensitivity of the integrated cross section to the short-distance features of the two-nucleon local potentials is also studied.
