Radiative electron capture in the first-forbidden unique decay of 81Kr
Artikel i vetenskaplig tidskrift, 2010

The photon spectrum accompanying the orbital K-electron capture in the first-forbidden unique decay of 81Kr was measured. The total radiation intensity for photon energies larger than 50 keV was found to be 1.42(22)×10-4 per K capture. Both the shape of the spectrum and its intensity relative to the ordinary, nonradiative capture rate are compared to theoretical predictions. The best agreement is found for the recently developed model that employs the length gauge for the electromagnetic field.
