Evidence for nonequilibrium proton emission in a low-energy heavy-ion reaction - art. no. 024603

Correlation functions for p-p, p-d, p-alpha, d-alpha, and alpha-alpha were measured for the O-16+Al-27 system at a beam energy of 72 MeV. The detector array was centered at laboratory angle of 20 degrees. Compared to publishe d data obtained at larger scattering angles, an unexpected dependence on an gle is seen for the p-p channel. The observed anticorrelation is stronger a t more forward angles, which suggests that correlation functions are sensit ive to the specific reaction mechanisms producing the light-charged particl es.
