Abstract
It is shown that Bloch's solution for the nth order perturbation of the energy and the eigenvector in the Rayleigh-Schrödinger perturbation theory of non-degenerate, discrete levels can be expressed in a different form, of a kind suggested by Brueckner, and some advantages of the latter form are presented.Keywords
