Radiative Corrections to the 2E1 Decay Rate of the 2s-State in Hydrogen-Like Atoms
Savely G. Karshenboim, Vladimir G. Ivanov
Abstract
Radiative corrections to the 2E1 decay width of the 2s-state in the low-Z hydrogen-like system are examined within logarithmic approximation. The correction is found to be 2.025(1) alpha (Z alpha)2 / pi log(Z alpha)2 in units of the non-relativistic rate.
