The hydrogenic 2s-1s two-photon emission
Abstract
The authors give an analytical expression for the probability of the hydrogenic two-photon decay. The expression allows a very accurate description of the two-photon continuum. For the total hydrogen 2s→1s two-photon transition probability a value of A2q = 8.2249 s-1 is found.
