QUASIELASTIC DEUTERON-PROTON SCATTERING IN THE REACTION d(d,dp)n AT Ed = 52.3 MeV

Publisher Summary This chapter describes the investigation of the reaction d (d,dp)n at a higher deuteron energy of 52.3MeV. The experimental data demonstrated the dominance of quasifree deuteron–proton and deuteron–neutron scattering mechanisms. Additionally, a neutron–proton final state interaction (FSI) was observed obviously occurring in the triplet state of the neutron–proton system because the singlet state was isospin-forbidden. The emitted protons and deuterons were detected in coincidence with plastic scintillators at angles θ 3 and, θ 4 properly chosen to obtain a maximum cross-section for quasielastic scattering. Each coincidence event was characterized by the energies and the time-of-flight of each particle. The result of an angular distribution measurement was presented for the quasielastic proton–deuteron two-particle scattering obtained from the measured three particle reaction cross-section. The deviation at forward angles was explained in principle by the influence of the neutron–proton triplet FSI, which was observed in the coincidence spectra at forward angles.
