Molecular-structure calculations have been performed to obtain the adiabatic potentials for ground state and numerous excited states of alkali-metal--He systems. They use l-dependent pseudopotentials defined from spectroscopy data or scattering data to describe the e/sup -/-M/sup +/ and e/sup -/-He interactions (where M is any alkali-metal atom). Standard variational calculations are made, and a large basis set of Slater-type orbitals is used in order to ensure accuracy and stability of the results. Our results are discussed along with comparisons with other theoretical and experimental data. The overall agreement which has been obtained with all available experimental data indicates that significant improvements in the calculation of the M-He adiabatic potentials have been achieved by using an l-dependent pseudopotential technique.
