Production and Nuclear Interaction of Neutrons

Abstract

In the year 1930, Bothe and Becker discovered artificial nuclear γ-radiation. They bombarded Li, Be, B, and other light elements with α-particles from a polonium preparation and with a needle counter observed γ-rays, whose energies they determined by absorption in lead as roughly equal to those of natural γ-rays. The γ-emission from the bombardment of Li was ascribed to nuclear excitation through inelastic scattering of the α-particles ; that of boron was explained by the fact that the residual C13 nucleus from the B10 (α, p) C13 reaction can be left in an excited state. Now, as then, both interpretations are considered correct. In the case of beryllium, which exhibited the most penetrating γ-radiation, Bothe and Becker hypothesized that nuclear excitation through capture of the α-particle occurred.
