Abstract
A recent paper by [Nascimento et al., Phys. Rev. A 74, 054501 (2006)], and a previous paper from the same group [de Oliveira et al., Phys. Rev. A 65 031401(R) (2002)], report measurements of Rydberg lifetimes in rubidium in the range . In this Comment, we point out one apparent flaw of experimental technique in these papers that may lead to systematic errors in the results. We also clarify a point of theoretical interpretation used in these papers which suggests that the agreement between experiment and theory may not be as good as it seems.
