Mirror nuclei emission and isospin transport at intermediate energies

Isospin effects are studied in reactions induced by 40Ca projectiles at E/A=25 MeV on 40Ca, 48Ca and 46Ti targets. The N/Z of projectile-like, target-like and mid-velocity sources are probed by measuring isotopic (7Li/6Li and 9Be/7Be) and isobaric (7Li/7Be) yield ratios, for semi-peripheral events....

Sumario:Isospin effects are studied in reactions induced by 40Ca projectiles at E/A=25 MeV on 40Ca, 48Ca and 46Ti targets. The N/Z of projectile-like, target-like and mid-velocity sources are probed by measuring isotopic (7Li/6Li and 9Be/7Be) and isobaric (7Li/7Be) yield ratios, for semi-peripheral events. The presence of isospin diffusion and drift phenomena is observed. It seems indeed that the interaction time between projectile and target does not allow a complete charge equilibration between quasi-projectile and quasi-target sources.
