摘要：

We examine the question of whether choices between different perturbation expansions or different gauges require the introduction of time-odd (and hence odd-rank) operators in Judd-Ofelt theory. We show that with a careful application of a Rayleigh-Schrodinger perturbation expansion in the length gauge only even-rank operators are required.
