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

Обсуждение углового распределения протонов в дейтериевых экспериментах

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

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.

Riassunto

Si discutono in breve fenomenologicamente alcune cause sperimentali e fisiche dell'anisotropia dei protoni spettatori nei sistemi di laboratorio negli esperimenti della camera a bolle a deuterio. Le distribuzioni angolari dei protoni spettatori da una serie di esperimenti sono state esaminate e confrontate con il comportamento atteso. Si sottolinea che per la presenza di parecchi aspetti importanti non si può ottenere dalle distribuzioni osservate la prova diretta di un effetto singolo, come l'effetto di flusso, di cui è state affermata l'esistenza in alcune pubblicazioni.

Резюме

Феноменологически обсуждаются некоторые экспериментальные и физические причины анизотропии распределения протонов в лабораторной системе в дейтериевых экспериментах в пузырьковых камерах. Исследуются угловые распределения протонов из серии экспериментов. Результаты сравниваются с ожидаемым поведением. Отмечается, что из-за наличия некоторых важных аспектов из наблюденных распределений невозможно получить прямое подтверждение для эффекта потока, о котором упоминалось в некоторых публикациях.
