摘要: The 4s-1s two-quantum decay in the hydrogen atom is calculated framework of quantum electrodynamics with allowance for cascades. It shown that pure two-photon contribution cannot be separated from cascade processes. Interference between transitions these two types comparable magnitude contribution. separation contributions discussed recently connection role decays radiation matter early Universe.
