Abstract

A spark-chamber missing-mass spectrometer was used to measure the differential cross section for the reaction

p + p \to d + π^{+}

at closely spaced intervals of incident momentum between 3.4 and 12.3 GeV/c and at small c.m. angle. The data confirm the existence of a prominent peak in the forward cross section at

E_{c . m .} ≃ 2.9

GeV and show a hitherto unreported shoulder at

E_{c . m .} ≃ 3.6

GeV. The results make evident the inadequacies of present one-pion-exchange and one-nucleon-exchange models.
