Abstract
Experiments on the reaction:3He+3He→4He+2He using a single four detector telescope have shown evidence for the production of deuteron pulses, consistent with the2He→2H+e++v fusion reaction in the final state. New measurements on the same reaction using improved techniques viz.A) a windowless3He gas target andB) α- d correlation detection with 5 ns resolving time and antipileup circuitry have been performed. Calibrations were obtained from the7Li+3He→2H+4He+4He reaction spectra. The correlation angles were 30° and 97° for the alphas and deuterons respectively. Deuteron pulses have been observed, correlated with alpha particles. A cross section of (1.7 ±0.5)nbsr−1MeV−1 was obtained consistent with previous measurements using a single telescope.
