Abstract

The spectrum of internal bremsstrahlung from the superallowed beta emitter 6He has been measured using a NaI scintillation spectrometer. The shape of the experimental spectrum agrees with the theory of Knipp, Uhlenbeck and Bloch for energies greater than 0.3 MeV. In this decay, Coulomb corrections are of little significance; thus the results can be interpreted as confirming the fundamental concept of internal bremsstrahlung as a process in which the electron exists first in a virtual state and then goes to its final state by emitting a photon.
