The coherent droplet model and the phase of the charge exchange scattering amplitude

Когерентная капельная модель и фаза амплитуды рассеяния с перезарядкой

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

Summary

The behaviour of the phase of the charge exchange scattering amplitude at varying trasfer momentum is deduced from the difference between the {ei489-1} and {ei489-2} elastic differential cross-sections. Such a behaviour suggests an improvement of Byers and Yang's coherent droplet model, thanks to the introduction of a suitable, anisotropic, parton-parton scattering amplitude.

Riassunto

Il comportamento della fase dell'ampiezza di diffusione di scambio carica al variare dell'impulso trasferito è dedotto a partire dalla differenza tra la sezione d'urto differenziale elastica di pioni positivi su protoni e quella di pioni negativi su protoni. Tale comportamento suggerisce un miglioramento del modello a gocciolina coerente di Byers e Yang, introducendo un'opportuna ampiezza di diffusione partone-partone anisotropa.

Резюме

Из разницы дифференциальных поперечных сечений упругих {ei495-1} и {ei495-2} рассеяний выводится поведение фазы амплитуды рассеяния с перезарядкой при различных переданных импульсах. Такое поведение предполагает усовершенствование когерентной капельной модели Байрса и Янга благодаря введению соответствующей анизотропной, партон-партонной амплитуды рассеяния.
