The gamma-radiation from boron bombarded by deuterons

Abstract

By a method already described, the gamma-ray spectrum from B+D has been obtained by observing the positron-electron pairs ejected from a thin lead lamina (0.033 cm) and the recoil electrons from a carbon lamina (0.12 cm). Gamma-ray components with quantum energies 1.5±0.2, 2.2±0.3, 4.4±0.3, 6.9±0.4 and 9.1±0.4 Mev are indicated with relative intensities >2.5: 2.5: 1.0: 0.3: 0.1. An attempt is made to correlate the energies and relative intensities of the observed gamma-ray components with those of the proton and neutron groups.
