ELECTROMAGNETIC EFFECTS IN LIGHT-NUCLEI AND THE CLUSTER POTENTIAL MODEL

Photodisintegration and radiative capture in the (NH)-H-2, (NH)-H-3, ( NHe)-He-3, (HH)-H-2-H-2, (KHe)-K-2-He-3, (HHe)-H-2-He-4, (HeH)-He-3-H- 3, (HeH)-He-4-H-3, and (HeHe)-He-4-He-3 channels are studied on the ba sis of the corresponding two-cluster potential models. The astrophysic al S factors at low energies are calculated. It is shown that various electromagnetic characteristics of light nuclei, including the Coulomb form factors at momenta of up to 4 F-1, can be studied using a single set of intercluster interactions containing forbidden states and cons istent with the phase shifts of the cluster low-energy elastic scatter ing. The calculated inelastic form factors have a second maximum at 3- 4 F-1 although it is lower than the experimental one. The orbital stat es are classified for the lightest cluster systems, and the phase shif ts and intercluster potentials are separated on the basis of Young orb ital schemes.
