| Abstract: | We have developed simple wave functions for two- and three-electron atoms and ions, which have the correct structure when one of the electrons is far away, or when two of the particles are close to each other. These essentially parameter-free wave functions allow us to deduce fairly accurate values for the energies, [r(2n)], for multipolar polarizabilities of two-electron atoms and ions, and for the coefficients of the asymptotic density. |
