摘要：
The Dalgarno-Lewis summation technique as used in the Rayleigh-Schrodinger perturbation theory is examined. It is shown that this technique forms an independent perturbation theory and can be used to deal with both bound- and continuum-state problems with some added advantage over other such approaches.
