Abstract

Results are presented for the region of squared four-momentum transfers between −0.05 and −0.5 (GeV/c)2. The directions of the scattered pions and alpha particles were measured with spark chambers and the momentum of the alphas as obtained from pulse-height and time-of-flight measurements. The results are compared with calculations from the Glauber theory, showing good agreement over the whole momentum-transfer range including the interference-dip region.
