Collisions of Alpha-Particles in Deuterium

Abstract

An investigation is made of the yields of deuterons emitted from deuterium under bombardment by alpha-particles from a polonium source. Three different but complementary experimental arrangements are employed: (1) The yield of deuterons projected forward is measured as a function of the alpha-particle velocity, the impinging alpha-particles being of nearly homogeneous velocity. (2) Absorption measurements are made on the deuterons projected forward by alpha-particles of all velocities up to the polonium limit. The results are found to agree with those of (1). (3) The yield of deuterons is measured as a function of the angle of projection for two different alpha-particle velocities.
