Abstract：
The isotopic distribution for DIR yields has been obtained for very asymmetricsystem ⁴⁰Ar(E_1ab=263MeV) + ²³⁸U. The fragment identification was done by the com-bination of two independent time of flight and two ΔE-E measurements. A simple classical model is presented to explain the experimental results for theN/Z degree of freedom. This model has also been tested for experimental results forvery asymmetric systems (⁴⁰Ar+¹⁹⁷Au, ³²S+²³⁸U, ⁶³Cu+²³²Th and ⁴⁰Ar+²³²Th) reportedby other authors. The agreement between this classical calculation and all the experi-mental results appears to be satisfactory.
