Potential energy of interaction between an electron and a molecule on the basis of slater atomic orbitals

This paper presents general analytical expressions derived for the potential energy of the interaction between an electron and a molecule and the 2 /sup L/ -pole electric moments of the molecules by the Hartree-Fock-Rutan method. These formulas are used for a machine calculation of the interaction potential between an electron and hydrogen and nitrogen molecules with different electron distances from these molecules and also of the electric multipole moments of a series of diatomic molecules with L = 0,1,2,3.
