Abstract
The transverse electron scattering form factors have been studied for low –lying excited states of 7Li nucleus. These states are specified by J^π T=1^-/2 1/2 (0.478MeV), 7^-/2 1/2(4.63MeV) and 5^-/2 1/2 (6.68MeV). The transitions to these states are taking place by both isoscalar and isovector components. These form factors have been analyzed in the framework of the multi-nucleon configuration mixing of harmonic oscillator shell model with size parameter brms=1.74fm. The universal two-body of Cohen-Kurath is used to generate the 1p-shell wave functions. The core polarization effects are included in the calculations through effective g-factors and resolved many discrepancies with experiments. A higher configuration effect outside the 1p-shell model space, such as the 2p-shell, enhances the form factors for q-values and reproduces the data. The present results are compared with other theoretical models.
