Abstract By using the full core plus correlation method recently developed, the accurately analytical charge densities for the lithium-like systems (Z=3-8) are obtained. The convergence pattern of the charge densities is analyzed. The electron-nuclear cusp condition is calculated for these systems. Also, at the region far from the nucleus, the behavior of the electron density is examined. The present calculations show that the wave functions used in this work can give the satisfactory and self-consistent results in full configuration space.
