Application of the stabilization method to the molecular states of LiHe3+: Energies and radial couplings.

Abstract

We have used the stabilization method to perform calculations on autoionizing states of the ${\mathrm{LiHe}}^{3+}$ system which are involved in ${\mathrm{Li}}^{3+}$+He collisions. The molecular energies and radial couplings are calculated with use of programs developed at our laboratory. For both short and large internuclear distances, the stabilization treatment is complemented by block-diagonalization techniques. Our calculations allow us to draw conclusions on the conditions under which these methods can be used to calculate energy positions and radial couplings for states that lie in an ionization continuum.
