High-energy {gamma} rays from targets of Be, C, and Al bombarded with 65 MeV {sup 3}He ions have been measured by the use of a {gamma}-ray detector system consisting of seven BaF{sub 2} scintillators. The energy spectra were obtained up to the maximum energy kinematically permitted in each collision at detection angles of 35{degree}{endash}144{degree}. The experimental cross sections are compared with calculations of the potential bremsstrahlung on which the theory has been developed by Nakayama and Bertsch. It is shown that the prediction of potential bremsstrahlung can well reproduce the production cross sections of {gamma} rays of energy near the kinematical maximum energy in collisions, while this result is contrary to the previous one of Tam {ital et} {ital al}. in {alpha} and {ital d} bombardments. {copyright} {ital 1996 The American Physical Society.}
