Abstract

Absolute coincidence cross sections were measured for the reaction 3He(d, tp)p at Ed = 20.7 MeV. Deep minima were observed in the cross sections when the relative energy of either p+p or t+p was below ≈ 20 keV. Predictions of the Watson-Migdal theory and of the PWBA and DWBA theories of Henley, Richards and Yu gave good agreement with the shapes of the spectra near these minima, but the required normalization factors varied widely from one geometry to another. Decay of the 21.2 MeV 4He state, but not the 20.0 MeV state, was observed.
