Energy spectra of light charged particles and evaporation residues in heavy ion induced reactions at low energy

Using a unified description on multiplicity distributions of final-state particles, the energy spectra of light charged particles and evaporation residues in heavy ion induced reactions at low energy are studied in the framework of a multisource ideal gas model. Each source in an excited composite contributes energy spectra of light charged particles and evaporation residues to be an exponential law. The calculated results are compared and found to be in agreement with the experimental data of inclusive and exclusive energy distributions for light charged particles and evaporation residues measured in the 20Ne (158, 170, 180, and 200 MeV) + 12C reactions.
