Abstract

Fragments produced in binary splits of an excited projectile-like fragment (PLF∗) formed in the reactions 124Xe + 112,124Sn at an incident energy of 50 MeV/A are examined. The dependence of the isotopic composition of light fragments (4 < ZL < 8) on rotation angle allows one to explore changes in N/Z on the time scale of the rotational period of the PLF∗. Changes in the N/Z of the fragments persist for times as long as 2-3 zs (600-900 fm/c). The two-component nature of the time dependence of N /Z for ZL = 4 and the Z dependence are related to differences in the initial configurations and subsequent decay of the PLF∗.
