Title: Radiative orbital electron capture by the atomic nucleus

Abstract

The rate for the photon emission accompanying orbital 1S electron capture by the atomic nucleus is recalculated. While a photon can be emitted by the electron or by the nucleus, the use of the length gauge significantly suppresses the nuclear contribution. Our calculations resolve the long standing discrepancy of theoretical predictions with experimental data for {delta}J=2 forbidden transitions. We illustrate the results by comparison with the data established experimentally for the first forbidden unique decays of {sup 41}Ca and {sup 204}Tl.
