Radiative Corrections to the 2E1 Decay Rate of the 2s-State in Hydrogen-Like Atoms

TL;DR

This paper calculates the radiative corrections to the decay rate of the 2s state in hydrogen-like atoms, providing a logarithmic approximation that refines previous theoretical models.

Contribution

It introduces a logarithmic approximation for radiative corrections to the 2E1 decay width in low-Z hydrogen-like systems, enhancing theoretical accuracy.

Findings

Correction is approximately 2.025 alpha (Z alpha)^2 / pi log(Z alpha)^2

The correction refines the decay rate calculations for the 2s state

Results are applicable to low-Z hydrogen-like atoms.

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.
