Internal Bremsstrahlung Accompanying the Positon Decay of 82Rb

Abstract: The internal bremsstrahlung from the positon decay of 82Rb has been measured in the energy ranges 0.95-1.3 and 1.7-2.0 MeV. The measured intensity was about twice the value predicted by the charge-independent theory. The external bremsstrahlung produced in stopping the positons in Be, C and Al has been measured in the same energy intervals. Energies and intensities of the γ-rays from 82Rb have been determined, and a revised energy level diagram is proposed for 82Kr. Some of the γ-rays were observed for the first time.
