Title: Isospin transport effects in nuclear reactions at 25 MeV/nucleon

Abstract

Isotopic effects are studied in reactions induced by {sup 40}Ca projectiles at 25 MeV/nucleon on {sup 40}Ca, {sup 48}Ca , and {sup 46}Ti targets. The N/Z contents of projectilelike and midvelocity (MV) sources are probed by means of isotopic ({sup 7}Li/{sup 6}Li and {sup 9}Be/{sup 7}Be) and isobaric ({sup 7}Li/{sup 7}Be) 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.
