Study of the spectra of fast deuterons produced in the interaction of 670 MeV protons with nuclei

Abstract The spectra of deuterons emitted at angles of 6.5°, 9.5°, 13.5° and 16° (lab system) in the interaction of protons with the nuclei 1 H, 2 H, 6 Li, 7 Li, C, Al, Cu, Rh and Pb have been measured in the momentum range 700–1700 MeV/ c . The secondary particles were analyzed with the help of magnetic and time-of-flight spectrometers. The differential cross sections for deuteron production in the reactions p + 〈2N〉 → N + d and p + 〈N〉 → d + π have been measured for selected nuclei and angles. The effective numbers of nucleons and of two-nucleon clusters for the investigated nuclei were determined. The results obtained are discussed in terms of the dispersion theory of direct nuclear reactions.
