The {sup 4}He({sup 4}He,{sup 3}He){sup 5}He(g.s.) reaction was observed at 118 MeV for c.m. angles from about 30{degree} to 120{degree}. DWBA calculations accurately predict the shapes of the {sup 3}He spectra for {epsilon}{sub {alpha}{ital n}}{le}2.5 MeV, where {epsilon}{sub {alpha}{ital n}} is the relative energy of the final {alpha}-{ital 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{degree} c.m. than the theory predicts.
