摘要：
We study the single-particle and the electron-pair densities for the ground state of two-electron atomic systems by means of wavefunctions which provide very good values for the energy. Special attention is paid to the convergence of some properties of the densities when we increase the dimension of the used basis. The best results obtained for the densities and for Kato's cusp conditions indicate that we have really got a quite goad description for the ground-state wavefunction.
