LIGHT CLUSTERS EMISSION IN NUCLEAR REACTIONS AT 25 MeV/NUCLEON WITH DIFFERENT N/Z OF ENTRANCE CHANNELS.

We discuss results on the emission of light clusters in nuclear reactions ⁴⁰Ca + ^40,48Ca,⁴⁶Ti at 25 MeV/nucleon. They were detected and identified in mass and charge by means of the CHIMERA 4π array. Inclusive emission at forward angles shows that isotopic yields of Li and Be nuclei are related to the N/Z values of entrance channels. Moreover, structure effects and even-odd staggering in charge distributions of intermediate mass fragments emitted at forward angles will be shown. In agreement with previous experimental findings, odd-even effects are clearly visible in N ≈ Z systems, while are less pronounced in the neutron rich collision ⁴⁰Ca+⁴⁸Ca. These experimental findings are compared to preliminary data obtained in ⁴⁰Ca+⁴⁸Ca. collision at 25 MeV/nucleon. [ABSTRACT FROM AUTHOR]
