摘要：

The charged particle identification obtained by the analysis of signals coming from the CsI(Tl) detectors of the CHIMERA 4pi heavy-ion detector is presented. A simple double-gate integration method. with the use of the cyclotron radiofrequency as reference time, results in low thresholds for isotopic particle identification. The dependence of the identification quality on the gate generation timing is discussed. Isotopic identification of light ions up to Beryllium is clearly seen. For the first time also the identification of Z = 5 particles is observed. The identification of neutrons interacting with CsI(Tl) by (n,alpha) and (n,gamma) reactions is also discussed.
