PHOTONUCLEAR REACTIONS IN C-12 AND SI-28

The giant dipole resonance in C-12 and Si-28 is studied in the frame o f the continuum random-phase-approximation theory. The behaviour of th e resonance is analized for a momentum dependent particle-hole interac tion of the Skyrme form. The predictions of the theory for the total p hotonuclear cross section and other photonuclear processes using diffe rent parametrizations of the p-h interaction are studied and the exper imental data are compared with the calculations performed with the Sky rme-parametrization that best fits them.
