Phys. Rev. A 38, 2189–2191 (1988)Comment on ‘‘Lifetime of excited atomic states’’Received 17 February 1988; published in the issue dated August 1988 We show that the two-photon nonresonant contribution to the lifetime of excited 3s and 3d states of hydrogen, as given by a formula recently derived by Cresser et al. [Phys. Rev. A 33, 1677 (1986)], can be evaluated in an economic way using the analytic expressions of the amplitudes of 3s-1s and 3d-1s two-photon transitions. Our numerical evaluation confirms the numbers given by Cresser et al. © 1988 The American Physical Society URL:
