Abstract
The range of the alpha-particles emitted from under 200 and 240 kv proton bombardment was measured at various angles with respect to the incident beam of protons. The results are fully in accord with the predictions of the principles of conservation of energy and momentum when the straggling due to the penetration of the target by the proton beam is taken into account. The results show, furthermore, that if is formed in this reaction, and subsequently disintegrates into two alpha-particles without the emission of a gamma-ray, it must have a mean life of not more than 3· second.
