Deep inelastic transfer reactions — The new type of reactions between complex nuclei

Extreme quadrupole deformation and clusterization

“…We incorporate it in two different ways: i) by applying simple bindingenergy arguments [25], and ii) by performing double-folding calculations, according to the dinuclear system model [26,27]. In this model the charge (mass) asymmetry…”

“…The energetic preference of the cluster configurations were obtained from binding-energy arguments [25], and from calculations based on the Dinuclear System Model [26]. The latter ones were performed both for the poleto-pole configurations and for the ones derived from the microscopic considerations.…”

Towards relativistic heavy ion collisions “by small steps towards the stars”

“…In Fig. 1.21 the distribution of magnesium isotopes is com pared at a very low energy of 5 MeV/nucleon (Volkov, 1978) and at 200 MeV/nucleon. We notice that the peak of the distribution shifts from an N/Z value characteristic of the dinuclear complex in deeply inelastic scatter ing, to a value closer to the projectile due to the abrasion process (remember that both distributions are perturbed by the secondary decays) (Bondorf, 1973).…”

“…At low energies of 6.5 and 10 MeV/nucleon the Z, or equivalently the mass, dispersion is gaussian (Volkov, 1978) governed by statistical diffusion processes in deeply inelastic scattering; at 200 MeV/nucleon and 1.8 GeV/ nucleon the distribution of fragments from Argon to oxygen;becomes essentially flat. This feature is also characteristic ) pf s Fe :!…”

“…As illustrated schematically, a dinuclear complex may be formed, and a characteristic time can be associated with the evolution of various collective modes. Estimates of the relaxation times provide a natural hier archy for categorizing the various degrees of freedom, suc.h as the energy of relative motion, the n-p ratio, the rotational degrees of freedom and the mass asymnetry (for reviews, Bee Schroder, 1977;Volkov, 1978;Weidenmuller, 1978 andLefort, 1978). As the energy is increased this process must merge into the still peripheral mechanism of abrasion and ablation (also illustrated schematically on the right).…”
