How accurately can we measure the hydrogen 2S->1S transition rate from the cosmological data?
arXiv:1205.5949 · doi:10.1088/1475-7516/2012/06/040
Abstract
Recent progress in observational cosmology, and especially the forthcoming PLANCK mission data, open new directions in so-called precision cosmology. In this paper we illustrate this statement considering the accuracy of cosmological determination of the two-quanta decay rate of 2s hydrogen atom state. We show that the PLANCK data will allow us to measure this decay rate significantly better than in the laboratory experiments.
