The electron density at the nucleus,p(0),and the radtial expectation values,＜ ＞(-2 ≤ n ≤10),of the ground state for the lithium isoelectronic sequence are calculated with a full core plus correlation(FCPC) wavefunctions.By using these obtained expectation values,the accurate inequalities of the electron density at the nucleus and the radtial expectation values derived by Galvez and Porras for these systems are examined and verified.The final results show that FCPC wavefunctions used in this work can give satisfactory results in full configuration space.
