Effect of Nuclear Forces on the Cross Sections of Photonuclear Reactions
Abstract
The effect of nuclear forces, or the effect of the quasideuteron model, is discussed for the integrated cross section and the bremsstrahlung weighted cross section. The nuclear force is assumed to be of partly Majorana exchange character. Only the central force is considered. The twobody potential is a Gaussian type without a hard core, the parameters of which are taken from the effective range theory. The calculations are performed by firstorder perturbation theory and the results are that the integrated cross section is increased by about ten percent and the bremsstrahlung weighted cross section is decreased by a few percent. Therefore the independentparticle model can be regarded as a good approximation for photonuclear reactions.
