Measurement of π+d-->Δ++n at intermediate energy
Abstract
The threefold differential cross sections for the reaction π+d-->Δ++n-->π+pn were measured in a kinematically complete experiment as a function of beam momentum and the Δ(1232) production angle. The cross sections were measured at seven beam momenta between 312 and 600 MeV/c for θΔ=55° and 91° in the center-of-mass system. Angular distributions from 30° to 119° (c.m.) were taken at beam momenta of 350 and 425 MeV/c. These data are compared with predictions from a unitary, relativistic, three-body theory based on the Faddeev equations and with a multiple scattering theory. The theories reproduce the general trend of the data except at the highest energies.
