摘要：

Light charged particles (p,d, t,He-3,He- 4) emitted in the reaction Ar-40+Al-27 at 60A MeV have been studied in a large angular range, 15 degrees<theta<112.5 degrees. The data have been analyzed by supposing light charged particle emission from three equilibrated sources. Although the ''temperatures'' of the three sources as extracted from the slopes of the energy spectra are in agreement with other existing data, they are much higher than those extracted from the isotopic ratios; The anomalous abundance of alpha particles is also stressed and discussed.
