摘要：

Based on the standard cosmological model, we calculate the correction to the rate of two-photon 2s <-> 1s transitions in the hydrogen atom under primordial hydrogen plasma recombination conditions that arises when the induced transitions under equilibrium background radiation with a blackbody spectrum and plasma recombination radiation are taken into account.
