A discussion of the angular distribution of spectator protons in deuterium experiments

Abstract

Several experimental and physical reasons for laboratory system anisotropy of spectator protons in deuterium bubble chamber experiments are briefly discussed phenomenologically. The angular distributions of the proton spectator from a series of experiments have been examined and compared with the expected behaviour. It is pointed out that, due to the presence of several important aspects, one cannot from the observed distributions obtain direct evidence for one single of these effects such as the flux effect, which has been claimed in some publications.
