Deuteron breakup with 3He at 89.4 and 118.9 MeV

Abstract Quasifree processes were studied by measuring coincident energy spectra for the 2 H( 3 He, 3 Hep)n, 2 H( 3 He, tp)p and 2 H( 3 He, dd)p reactions at 89.4 and 118.9MeV. The spectral shape was reproduced with two types of spectator model, that is, a three-body model (TBM) and a four-body model (FBM). The latter contains the effects of projectile breakup processes. Angular correlations of peak cross sections were explained by calculations in the FBM in contrast with those in the TBM. The absolute cross sections were not explained by either model.
