LI-6 ELECTROMAGNETIC FORM-FACTORS AND PHENOMENOLOGICAL CLUSTER MODELS

The longitudinal form factors of the ground and 2.18 MeV (3+, T = 0) states, and the transverse form factors of the 3.56 MeV (0+, T = 1) and 5.37 MeV (2+, T = 1) states of 6Li are compared with the predictions based on fully antisymmetrized α-d and t-τ cluster models. The longitudinal form factors are adequately described by the α-d model, but the transverse form factors seem to be more consistent with a t-τ model which is close to the shell-model limit. Estimates are made for the ground state t and α spectroscopic factors. The 3.56 MeV M1 transition current density is calculated for both models and compared with experiment. © 1979.
