RADIAL ELECTRONIC DENSITY FOR THE GROUND-STATE OF THE LITHIUM ISOELECTRONIC SEQUENCE

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 i s analyzed. The electron-nuclear cusp condition is calculated for thes e systems. Also, at the region far from the nucleus, the behavior of t he electron density is examined. The present calculations show that th e wave functions used in this work can give the satisfactory and self- consistent results in fun configuration space.
