Abstract
Accompanying capture, as in -activity, there is a weak continuous high energy gamma-ray spectrum. The major contribution to the effect is from magnetic radiative capture of a electron. For an allowed transition using Fermi or Gamow-Teller coupling, the number of gamma-quanta per electron captured is , where is the available energy. For other couplings and forbidden transitions, the effect is of the same order of magnitude.
