Calculations based upon the Faddeev equations and measurements of proton-induced deuteron disintegration cross sections have been mad& at 23.0 and 39.5 MeV for two types of constant-relative-energy loci. In the first configuration the variation of the breakup cross section was studied for fixed values of the final state NN relative energies and a fixed momentum of one of the emerging protons. In the second configuration the variation of the breakup cross section was studied for equal relative energies between all three pairs of nucleons with the two protons emerging with equal momenta symmetrically with respect to the incident beam direction. At 39.5 MeV calculations and measurements were made of both types of loci while at 23.0 MeV only the second kinematical configuration was studied, NUCLEAB BEACTIONS 2H(P, 2P) n at T&=23.0 and 39.5 MeV, measured two types of constantrelative-energy loci; comparisons with three-body calculations using the Beid soft-core potential.
