Abstract

Energy spectra of quasielastic reaction products formed in ⁸⁶Kr bombardment of ²⁰⁸Pb at various beam energies show broad structures that are shown to originate from sequential neutron emission following one- or few-nucleon transfer. A Monte Carlo simulation of the decay process is used to obtain information on the excitation energy sharing for primary fragments. Strong evidence is found for a channel-dependent sharing of the excitation energy among the reaction partners.

Fission: A filter for the study of nuclear reaction mechanisms
1989, Nuclear Physics, Section A
The use of nuclear fission as a reaction filter to study the dynamics of low-to-intermediate energy nucleus-nucleus collisions has been widely exploited over the past decade. In particular, the fission fragment angular correlation (folding-angle) technique has been utilized to derive an understanding of linear momentum and energy transfer in projectile-nucleus interactions. These results illustrate the systematic evolution in reaction mechanisms from relatively simple processes such as complete fusion and peripheral transfer reactions at near-barrier bombarding energies to highly complex interactions dominated by precompound processes at intermediate energies. Studies of light charged particles, neutrons and complex fragments in coincidence with fission-tagged events demonstrate the growing influence of nucleon-nucleon collision mechanisms relative to the dinuclear mean field in determining the reaction dynamics with increasing projectile energy. The application of these same techniques to the investigation of the inverse fission process--damped collisions--has also yielded important new insights into this class of reactions and recent results for nuclide distributions and excitation energy sharing are described.
Fast dissipative collisions
1988, Nuclear Physics, Section A
At a bombarding energy of 14.7 MeV/u the charge, mass and angular distributions have been measured as a function of energy loss for reaction products induced by ⁹⁸Mo and ⁹²Mo projectiles on targets of ⁹⁸Mo, ¹⁴⁷Sm, ¹⁵⁴Sm and ⁹²Mo, ¹⁵⁴Sm, ²³⁸U, respectively. An analysis of the product distributions shows the presence of a non-equilibrium sharing of the excitation energy, an exponential growth of the charge and mass variances, a complete $N Z$ equilibration and a large yield of non-binary complex fragments. Monte Carlo simulations are found to be an indispensable tool of the analysis.
