The Li6 nucleus is investigated in the projected Hartree-Fock model. In view of the partial successes of the deformed Hartree-Fock and the cluster models, we attempt extension of the deformed orbits and construction of the molecule-like orbits. Energy variation and the calculation of the elastic and inelastic charge form factors are carried out in both the extended deformed orbits and the newly introduced molecule-like orbits. Conventional effective two-body forces are assumed in energy calculations. The results are compared with experiment and detailed discussions are made on the comparative merits of the above two orbits. Expansion of the Hartree-Fock states in terms of the shell-model configurations is presented. The use of the density-dependent forces is discussed in connection with the underbinding of Li6.
