Abstract
The differential cross section of the pp → πd reaction was measured for seven energies between 516 and 582 MeV with an overall absolute precision better than 2%. Pions and deuterons were detected in coincidence with scintillation detectors, using time-of-flight techniques for event identification. Experimental techniques for absolute energy calibration, normalization and measurement of relative distributions are described. Detailed corrections have been applied to the data, which have been fit with Legendre polynomials. An upper limit of 50 μb for a sixth-order term is obtained. The results are compared with those of a recent precision experiment for the inverse reaction, and with theoretical predictions.
