Summary
We present differential cross-sections for\(\bar pp\) elastic scattering for cosθc.m.<0 at six laboratory momenta from 686 MeV/c to 1098 MeV/c. The data are dominated by the secondary diffraction peak which moves slowly to larger values of |t| as the beam momentum increases. There is no evidence for a third diffraction peak or for direct-channel effects in these data.
Riassunto
Si presentano delle sezioni d’urto differenziali relative allo scattering elastico\(\bar pp\) per cosθc.m.<0 e per sei valori dell’impulso nel laboratorio da 686 MeV/c a 1098 MeV/c. I dati mostrano la dominanza del picco secondario di diffrazione che si muove leggermente verso i valori crescenti di |t| quando l’impulso del fascio cresce. Non appaiono dai dati né un terzo picco di diffrazione né effetti di canale diretto.
Реэюме
Мы предлагаем дифференциальные поперечные сечения для\(\bar pp\) упругого рассеяния для сов θц.м.<0 при щести эначениях лабораторного импульса от 686 MзB/c до 1098 MзB/c. Полученные данные, в основном, обусловлены вторичным дифракционным пиком, который медленно движется в сторону больщих эначений |t|, когда импульс пучка увеличивается. Не обнаружено подтверждений ни для третьего дифракционного пика, ни для зффектов прямого канала в зтих данных.

Prof. W. CHINOWSKY was generous in extending to us the hospitality of LBL in the early stages of the analysis. Finally, the AGS and 30 inch bubble chamber staffs were essential to the performance of this work.
