Properties of the Metastable Helium Atoms
A. Dalgarno, A E Kingston
The available theoretical values of the oscillator strengths of dipole transitions from each of the metastable states of helium are modified so that each set satisfies four different sum rules. They are then employed to evaluate the polarizabilities, the diamagnetic susceptibilities, the average energy losses for fast particle impact, the Lamb shift average excitation energies and the van der Waals interactions between normal and metastable helium atoms.
