Pion photoproduction revisited

Фоторождение пионов

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

Summary

A new semi-phenomenological analysis of the multipoles for pion photoproduction from protons, in the region of the first\(\pi - {\mathcal{N}}\) resonance is presented. Through an energy-dependent model, the multipoles with isospin 1/2 and 3/2 and total angular momentumJ≤3/2 are determined.

Riassunto

Sipresenta una nuova analisi semifenomenologica dei multipoli per la fotoproduzione di pioni da protoni, nella regione della prima risonanza\(\pi {\mathcal{N}}\). Si determinano i multipoli con isospin 1/2 e 3/2 e impulso singolare totaleJ≤3/2 attraverso un modello dipendente dall’energia.

Резюме

Проводится новый полуфеноменологический анализ мультиполей для фотороздения пионов на протонах в области первого\(\pi - {\mathcal{N}}\) резонанса. С помощью зависящей от энергии модели определяются мультиполи с изоспинами 1/2 и 3/2 и полным угловым моментомJ≤3/2.
