Microscopic Calculation of ⁶Li Elastic and Transition Form Factors

Variational Monte Carlo wave functions, obtained from a realistic Hamiltonian consisting of the Argonne v₁₈ two-nucleon and Urbana-IX three-nucleon interactions, are used to calculate the ⁶Li ground-state longitudinal and transverse form factors as well as transition form factors to the first four excited states. The charge and current operators include one- and two-body components, leading terms of which are constructed consistently with the two-nucleon interaction. The calculated form factors and radiative widths are in good agreement with available experimental data.
