“…The proton-deuteron radiative processes are interpreted by the following extension of the spectator model. 18 The incident proton interacts with one of the nucleons in the deuteron, which has a momentum distribution given by the deuteron wave function. The y ray is produced in this initial interaction, and does not interact further.…”

A knowledge of off-mass-shell behavior of the nucleon-nucleon interaction is very desirable, both as a test of various theoretical pictures 1 of the N-N interaction, and as input information for nuclear structure calculations. Nucleon-nucleon bremsstrahlung, N+N-+N + N+y, is a promising way to study such behavior, and for this reason £-/> bremsstrahlung (hereafter ppy) has received much attention in recent years, both experimental 2 " 6 and theoretical. 7 " 10 Although equally interesting, n-p bremsstrahlung (hereafter npy) has received much less attention. Calculations by Ashkin and Marshak 11 and by Cutkosky 12 suggest that the npy cross section is several times larger than the ppy cross section; however, calculations by Duck and Pearce 13 predict that the two cross sections are comparable. Experiments 14-16 studying the production of high-energy (>20-MeV) y rays from proton bombardment of complex nuclei have been interpreted in terms of npy inside the nucleus. However, Beckham 17 found that the extraction of the free npy cross section from such data is very uncertain and model dependent. The present work was undertaken to provide a more reliable npy cross-section measurement.The experiment was performed with a proton beam and a target of "almost free" neutrons in deuterium. (The alternative of using a neutron beam and a hydrogen target was discard-ed because a neutron beam combining sufficient intensity and energy definition was not available.) The proton-deuteron radiative processes are interpreted by the following extension of the spectator model. 18 The incident proton interacts with one of the nucleons in the deuteron, which has a momentum distribution given by the deuteron wave function. The y ray is produced in this initial interaction, and does not interact further. On occasions the spectator nucleon will interact with the incident or struck nucleon. These final-state interactions will distort the kinematics from those of the simple quasifree process, and sometimes cause binding of the interacting particles.

“…The experimental data on A(x, bx)B reactions have been analyzed using various models: plane wave [5] and distorted wave [32] impulse approximations (PWIA and DWIA), modified simple impulse approximation [33] (MSIA), several modifications of PWIA, higher order corrections [26] in particular S-state final state interaction modifications [3,27] of the PWIA, unitarized version of the truncated multiple scattering series [34], and the AMADO model [35 --38]. The purpose of this work is to critically evaluate these models, paying special attention to the quasifree scattering process.…”

Experimental data demonstrate that the enhancement associated with the quasi free kinematic conditions in nuclear reactions is one of the most prominent features in a large energy interval. The experimental data on A(x, bx)B reactions have been analysed using various models: plane wave and distorted wave impulse approximations (PWIA and DWIA), modified simple impulse approximation (MSIA), several modifications of PWIA, higher order corrections in particular S-state final state interaction modifications of the PWIA, unitarized version of the truncated multiple seattering series and the AMADO model.

The D(p t 2p)n cross section has been measured at E p = 39.5 MeV using a unique multidetector scattering chamber. The integrated cross section d A a/dQ A dE z dE A shows a prominent minimum due to destructive interference between the single-scattering term of the rescattering series and the higher order terms of the series. This destructive interference accounts for the failure of the simple impulse approximation to predict correctly the magnitude and shape of the quasifree scattering peak.
