Abstract

Products from the reactions of 170- and 252-MeV ${}^{20}{Ne}$ with ${}^{nat}{Cu}$ and ${}^{197}{Au}$ have been studied. The charge and angular distributions of the $Z$ -identified fragments are discussed in terms of diffusion along the mass-asymmetry coordinate. This diffusion model has been generalized to include the effects of shape evolution, which is important for these deeply penetrating systems, and also the effect of $\frac{N}{Z}$ equilibration, which is important for highly asymmetric systems such as ${}^{20}{Ne}$ + ${}^{197}{Au}$ .

NUCLEAR REACTIONS ${}^{nat}{Cu}$ , ${}^{197}{Au}$ ( ${}^{20}{Ne}$ , $Z$ ), $E = 170 and 252$ MeV. Measured $σ (E, Z, θ)$ , for $6 \leq Z \leq 30$ . Theoretical interpretation based on a diffusion model.
