Summary
We present a discussion of the energy-dependent behaviour of the proton-deuteron elastic scattering atϑ c.m.=180°. We show that the interference betweenS andP waves is mainly responsible for the low-energy peak. It is also pointed out that the present-day experimental information is not sufficient to support or rule out the alternative explanations for the higher-energy peak.
Riassunto
Si discute il comportamento dipendente dall’energia dello scattering elastico protonedeutone perϑ c.m.=180°. Si dimostra che il picco di bassa energia è determinato principalmente dall’interferenza tra ondeS eP. Inoltre si pone in evidenza che gli attuali dati sperimentali non sono sufficienti per sostenere o scartare le alternative interpretazioni proposte per il picco di alta energia.
Реэюме
Мы обсуждаем знергетическую эависимость упругого рассеяния про-тона на дейтроне наθ Ц.М.=180°. Мы покаэываем, что интерференция междуS иP волнами в основном ответственна эа пик при ниэких знергиях. Также отмечается, что имеюшаяся на сегоднящний день зкспериментальная информация недостаточна для подтверждения или исключения альтернативных общяснений для пика при высо-ких знергиях.

J. Chahoud, G. Russo andF. Selleri:Phys. Rev. Lett.,11, 506 (1963). The arguments presented in this paper are also applicable to the pd→dp scattering as both pp→dπ+ and pn→dπ0 contribute to the triangular graphc) of Fig. 2. Effect of pn→dπ0 is taken care of by the factor 3/2 in eq. (3).
Such a hypothesis was first advanced byV. A. Grishin andM. J. Podgoretskii: JINR-Report No. R-1508, Dubna (1964). See alsoL. A. Kondratyuk andI. S. Shapiro:Yad. Fiz.,12, 401 (1971) (Sov. Journ. Nucl. Phys.,12, 220 (1970).)
The indications are that the force between nucleon and Δ(1236) is strong enough to give rise to a dibaryon resonance in the (J p=2+,T=1) state. (The present situation for the existence of dibaryon resonances is reviewed byL. M. Libby andE. Predazzi:Lett. Nuovo Cimento,2, 881 (1969).) Therefore, it is appropriate to take the Δ(1236), instead of theN *(1688)-resonance, for the formation of the 3Δ He-state.
