CALCULATION OF COULOMB FORM-FACTORS OF LITHIUM NUCLEI IN A CLUSTER MODEL-BASED ON POTENTIALS WITH FORBIDDEN STATES

Elastic and inelastic Coulomb form factors of Li-6 and Li-7 nuclei are considered in the framework of alphad and alphat cluster models, resp ectively. Potentials with forbidden states, which describe main charac teristics of bound states and phase shifts of elastic scattering at lo w energies, are used as intercluster potentials. A good description of elastic form factors is obtained for momenta up to 4 fm-1. Although t he second maximum at 3-4 fm-1 is obtained in the calculated inelastic form factors, the amplitude of this maximum is smaller than the experi mental value. Probabilities of electromagnetic transitions and other e lectromagnetic characteristics are calculated.
