摘要：
The He-4(He-4,He-3)He-5(g.s.) reaction was observed at 118 MeV for c.m. angles from about 30-degrees to 120-degrees. Distorted wave Born approximation (DWBA) calculations accurately predict the shapes of the 3He spectra for epsilon(alphan) less-than-or-equal-to 2.5 MeV, where epsilon(alphan) is the relative energy of the final alpha-n system. However the measured differential cross sections are smaller than the DWBA predictions by about a factor of 2 at forward angles, and have a less pronounced minimum at 90-degrees c.m. than the theory predicts.
