摘要: By using the full-core plus correlation (FCPC) type wave functions, accurate charge densities (0) at nucleus and radial expectation values of ground states for lithium-like systems with Z = 21 to 30 are obtained. The determinantal conditions electron-nucleus cusp condition used calculate inequalities upper lower bounds two or more values. These inequalities, derived by Angulo Dehesa [Phys. Rev. A 44 1516 (1991)], verified be also valid these ions higher nuclear charge. present results show that functions in this paper satisfactory whole configuration space
