“…Such lifetimes are incompatible with the formation of an equilibrated compound nucleus, but may still reflect significant energy damping within the deepinelastic collision mechanism. It is possible to estimate the lifetime of the intermediate di-nuclear complex using a diffractive Regge-pole model [32,54] from these measured forward peaked angular distributions. The angular distributions have been fitted using the following expression, (dσ/dΩ) DI = (C/sinθ c.m.…”

Inclusive energy spectra of the complex fragments (3 ≤ Z ≤ 5) emitted in the reactions 12 C (77 MeV)+ 28 Si, 11 B (64 MeV)+ 28 Si and 12 C (73 MeV)+ 27 Al (all having the same excitation energy of ∼ 67 MeV), have been measured in the angular range of 10• . The fully energy damped (fusion-fission) and the partially energy damped (deep inelastic) components of the fragment energy spectra have been extracted. It has been found that the yields of the fully energy damped fragments for all the above reactions are in conformity with the respective statistical model predictions. The time scales of various deep inelastic fragment emissions have been extracted from the angular distribution data. The angular momentum dissipation in deep inelastic collisions has been estimated from the data and it has been found to be close to the corresponding sticking limit value.

“…At bombarding energies of up to a few tens of MeV/u, many reported experiments with heavy ions have involved the measurement of the angle, mass (or charge) and energy of reaction products [1][2][3][4][5]. By measuring the angle of emission of two fission fragments and the difference in their time-offlight, the entire kinematics can be reconstructed including the primary masses and the excitation energy.…”

The Monte Carlo method is employed to calculate the geometrical efficiency of a multi-detector system for fragments produced in heavy ion reactions. This efficiency is defined as a quotient of the number of fragments intercepted by the system and the total number of fragments emitted by the fissioning nucleus in all directions. The multi-detector system consists of six parallel-plate avalanche counters in a hexagonal configuration around the target. Its geometrical efficiency was calculated with respect to the 36Ar + 238U reaction at a 7 MeV/u projectile energy.

Comprehensive analysis of fusion data well above the barrier

et al. 2014

International audienceWe report on the comprehensive systematics of nearly 400 fusion-evaporation and/or fusion-fission cross-section data for a very large variety of systems over an energy range ∼3A to 155A MeV. Scaled by the reaction cross section and expressed as a function of the center-of-mass energy per nucleon, the fusion cross section displays a universal behavior. Within experimental errors, this behavior does not depend on system mass, mass asymmetry, or system isospin. The deduced homographic functional dependence for complete and summed complete and incomplete fusion excitation functions is derived from basic strong absorption model formulas for reaction cross sections and allows us to draw the main properties of these functions. The limiting energy for the complete fusion and the main characteristics (onset, maximum, and extinction) of the incomplete fusion excitation functions are determined. The complete fusion reaction process disappears around 6.5 MeV/nucleon and the incomplete one disappears at about 13 MeV/nucleon in the center-of-mass frame. The regularity in fusion data is particularly obvious for the evaporation-residue subset of the data ensemble. Adding the fusion-fission data component does not alter the general data trend but somewhat obscures it owing to the larger uncertainty and/or possible normalization problems
