Papers such as http://arxiv.org/PS_cache/arxiv/pdf/0904/0904.1503v2.pdf talk of 2 photon decay from 2s to 1s or 2p to 1s.
"The probabilities for the spontaneous two-photon decay in hydrogen atoms and hydrogen-like ions are under investigation since the theoretical formalism has been introduced by G¨oppert-Mayer [9] and the first evaluation for the two-photon E1E1 transition 2s → 2
(E1) + 1s has been presented by Breit and Teller [10]. A highly accurate calculation of the E1E1 - transition probability has been performed by Klarsfeld [11]. Recently Jentschura [12] performed a complete evaluation of the radiative corrections and presented more accurate value of the E1E1 two-photon decay probability. The double- and triple-photon decays
of metastable 3P0 atomic state were considered in [13]. The present paper is devoted also to evaluation of the probabilities for two-photon decays 2p → (E1) + (M1) + 1s and 2p → (E1) + (E2) + 1s."
I am unsure what it means. What are the wavelengths of the photons in question? Are they talking about the electron jumping to the 3rd level and falling twice? TIA.
