PION-PROTON ELASTIC SCATTERING FROM 3 GEV/C TO 5 GEV/C
Abstract
Results of a spark chamber experiment on elastic scattering of pions on protons are presented and analyzed. The processes studied were pi plus p at 2.92 GeV/c, and pi minus p at 3.15, 4.13, and 4.95 GeV/c. The data are fit to an exponential function of the four-momentum transfer, t, in several different ways in attempts to explore systematic energy and angular dependences. No shrinkage of the diffraction peak is seen in comparing the coefficients of a linear exponen tial fit for t absolute < 0.4 (GeV/c) squared; at larger t absolute, however, the cross section falls off with increasing energy. The large angle differential cross section is examined for structure, and is compared with all other large angle scattering data. The results are compared with proton-proton scattering data over the same energy range and substantial differences between the two processes are evident.
