“…Of course, the reaction mechanisms for tritons emitted in the forward and backward directions of the He z (d,t)2p reaction are different. Presumably, the forward mode is dominated by a pickup process, whereas the backward 66 The present status of the excited states in He 3 mode is dominated by a charge-exchange process. The larger absolute value of a pp which was required to fit the triton energy spectra at backward angles implies that the experimental peaks are narrower than those predicted by the Watson-Migdal model using the correct value for a pp .…”

At present the only means for obtaining information about the neutron-neutron scattering length a nn and effective range ro are studies of reactions with three or more particles in the final state. It was felt that the comparative analysis of the various reactions which exhibit a ^o nucleon-nucleon interaction in the final state would be a reliable procedure by which to extract a nn . Thus the nucleon-induced breakup reactions of deuterons and trions were analyzed using the Born approximation and S-state wave functions for the deuteron, the trion and the two nucleons having a low relative energy in the final state. We found the comparative analysis of the trion breakup processes unsuccessful in the energy range considered. The values for a nn extracted in analyses of the reaction D(n,p)2n around 14 MeV cannot be reconciled with the theoretical predictions based on exact charge symmetry and using either a hard-core or a velocity-dependent potential. The present analysis indicates, however, that for incident energies larger than 30 MeV the distorting interference effects are removed and that the deuteron breakup processes become more promising for the determination of a nn .

“…1 (a) the deuteron spectrum from the reaction H. 3 (n,d)2n 22 at an incident neutron energy of 14.4 MeV is compared with the results of calculations I and II. Calculation II (the dashed curve) produces a peak broader than, while calculation I (solid curves) produces a peak narrower than, the experimental one.…”
