Translational Absorption of HeH

摘要

There is reported here the calculation of the translational absorption spectrum of a system of a helium atom and a ground state hydrogen atom. We report also values of calculated potential curves for the ground state of the molecular system HeH and the dipole moment of the ground molecular state of HeH as a function of internuclear separation. The behavior of the dipole moment is of particular interest as it passes through zero at aboutRequals;7a0. This change of sign follows from and correlates with the known long range behavior of the dipole moment of this system.
