We discuss results on the emission of light clusters in nuclear reactions (40)Ca +(40,48) Ca,(46) Ti at 25 MeV/nucleon. They were detected and identified in mass and charge by means of the CHIMERA 4 pi 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 approximate to Z systems, while are less pronounced in the neutron rich collision (40)Ca +(48) Ca. These experimental findings are compared to preliminary data obtained in (48)Ca+(48) Ca collision at 25 MeV/nucleon.

Abstract
We discuss results on the emission of light clusters in nuclear reactions (40)Ca +(40,48) Ca,(46) Ti at 25 MeV/nucleon. They were detected and identified in mass and charge by means of the CHIMERA 4 pi 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 approximate to Z systems, while are less pronounced in the neutron rich collision (40)Ca +(48) Ca. These experimental findings are compared to preliminary data obtained in (48)Ca+(48) Ca collision at 25 MeV/nucleon.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
