Kurzbeschreibung (Abstract)
The recent observation of the competitive double-γ decay process is presented. It is a second-order electromagnetic decay mode. The 662-keV decay transition from the 11/2⁻ isomer of ¹³⁷Ba to its ground state has been studied. The emission of a single 662-keV γ quantum is a factor of 5 × 10⁵ more likely than the simultaneous emission of two γ quanta instead of one. The observed angular correlation and energy distribution of these rare coincident double-γ quanta are well described by a dominant M2 – E2 and a sub-dominant E3 – M1 contribution to the double-γ decay branch.
