Abstract

Inclusive deuteron spectra (d2σ/dΩdp) have been measured for the reaction np → dX at neutron energies of 1.0 and 2.0 GeV. A quasi-monochromatic neutron beam was used, along with a liquid hydrogen target. Recoil deuterons at laboratory angles from 3° to 15° were tracked in wire chambers surrounding a 1.5 T·m dipole magnetic field. Particle identification was achieved using time-of-flight and momentum measurements. The deuteron data are compared with the predictions of a one-nucleon-exchange model with σ meson production. At 2 GeV the missing mass spectra suggest the large role played by both the η and p mesons in deuteron production.
