Pion-induced knock-out reactions on4He

Реакции выбивания на4Не, индуцированные пионами

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

Summary

New experimental values of the ratio

$$\sigma \left( {^4 He(\pi ^ + ,\pi ^ + p)^3 H} \right)/\sigma \left( {^4 He(\pi ^ + ,\pi ^ + n)^3 He} \right) + \sigma \left( {^4 He(\pi ^ + ,\pi ^0 p)^3 He} \right)$$

are given atE labπ − 110 and 160 MeV. This ratio as well as the total and differential cross-sections of pion-induced knock-out reactions on4He are discussed in terms of simple theoretical models.

Riassunto

Si danno nuovi valori sperimentali del rapporto

$$\sigma \left( {^4 He(\pi ^ + ,\pi ^ + p)^3 H} \right)/\sigma \left( {^4 He(\pi ^ + ,\pi ^ + n)^3 He} \right) + \sigma \left( {^4 He(\pi ^ + ,\pi ^0 p)^3 He} \right)$$

alle energieE labπ − 110 e 160 MeV. Questo rapporto e le sezioni d’urto totali e differenziali delle reazioni di knock-out indotte da pioni su4He sono discussi in termini di semplici modelli teorici.

Реэюме

Приводятся новые зкспериментальные величины для отнощения

$$\sigma \left( {^4 He(\pi ^ + ,\pi ^ + p)^3 H} \right)/\sigma \left( {^4 He(\pi ^ + ,\pi ^ + n)^3 He} \right) + \sigma \left( {^4 He(\pi ^ + ,\pi ^0 p)^3 He} \right)$$

при {ie340-1}=110 и 160 МзВ. Обсуждаются зто отнощение, а также полное и дифференциальное сечения реакций выбивания на4Не, индуцированных пионами. Обсуждение проводится в рамках простых теоретических моделей.
