Isotopic effects are studied in reactions induced by Ca40 projectiles at 25 MeV/nucleon on Ca40, Ca48, and Ti46 targets. The N/Z contents of projectilelike and midvelocity (MV) sources are probed by means of isotopic (Li7/Li6 and Be9/Be7) and isobaric (Li7/Be7) yield ratios, for semiperipheral events. In particular, information about isospin transport phenomena will be discussed. Isospin diffusion processes involving nuclei, which have noticeable differences in N/Z have been investigated. Signals of isospin drift, which are related to the gradient of density in the participant region, have also been observed for fragments emitted at MV.

Abstract
Isotopic effects are studied in reactions induced by Ca40 projectiles at 25 MeV/nucleon on Ca40, Ca48, and Ti46 targets. The N/Z contents of projectilelike and midvelocity (MV) sources are probed by means of isotopic (Li7/Li6 and Be9/Be7) and isobaric (Li7/Be7) yield ratios, for semiperipheral events. In particular, information about isospin transport phenomena will be discussed. Isospin diffusion processes involving nuclei, which have noticeable differences in N/Z have been investigated. Signals of isospin drift, which are related to the gradient of density in the participant region, have also been observed for fragments emitted at MV.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
