Shakeup and shakeoff satellite structure in the electron spectrum of ${}^{83}$Kr${}^m$

Abstract

The isotope ${}^{83}$Kr${}^m$, a 1.8-hr isomer of stable ${}^{83}$Kr, has become a standard for the calibration of tritium beta decay experiments to determine neutrino mass. It is also widely used as a low-energy electron source for the calibration of dark-matter experiments. The nominally monoenergetic internal conversion lines are accompanied by shakeup and shakeoff satellites that modify the line shape. We draw on theoretical and experimental information to derive a quantitative description of the satellite spectrum of the K-conversion line.
