TL;DR: In this paper, the angular momentum misalignment for fragments produced in deep inelastic scattering is discussed in terms of the thermal excitation of angular-momentum-bearing modes in the intermediate complex.
24 citations
TL;DR: In this paper, a model is developed which allows one to calculate analytically the angular momentum removed, and the angular trajectory misalignment created by the evaporation of light particles from an excited nucleus.

TL;DR: In this article, the phase-space distributions of 3-body events were analyzed by means of an improved version of the kinematic coincidence method and it was shown that 3-and possibly 4-body body events predominantly originate from a two-step mechanism and are compatible with the hypothesis of a binary deep-inelastic interaction followed by the further fissionlike decay of one (or both) of the primary fragments.
Abstract: Events with 2, 3 and 4 heavy fragments (A≥20) detected in the reactions100Mo +100Mo at 18.7, 23.7 A·MeV and120Sn +120Sn at 18.4 A·MeV were analyzed by means of an improved version of the kinematic coincidence method. The phase-space distributions prove that 3- (and possibly 4-) body events predominantly originate from a two-step mechanism and are compatible with the hypothesis of a binary deep-inelastic interaction followed by the further fissionlike decay of one (or both) of the primary fragments. The characteristics of the fission step — mass asymmetry, relative velocity, in-plane and out-of-plane angles — have been reconstructed for the 3-body events and indications are found that nonequilibrium effects at the end of the deep-inelastic phase may influence the fissionlike decay.

TL;DR: In this paper, a two-sphere model is developed for the thermal excitation of spin-depolarizing modes in mass asymmetric heavy-ion systems, and the effect of these modes on the spin distributions and the spin alignment of the fragments is investigated.

TL;DR: The angular-momentum-bearing degrees of freedom involved in the fission process are identified and their influence on experimental observables is discussed in this article, where the excitation of these modes is treated in the ''thermal'' limit, and the resulting distributions of observables are calculated.

TL;DR: In this paper, a semiclassical analysis has been used to estimate the effective barriers to emission and root-mean-square spins of the emitters of 3.4He reactions.
Abstract: Angular and energy distributions have been measured for products of 3≦Z≦9 from reactions of 336MeV40Ar+107,9Ag/154Sm/197Au. The c.m. differential cross sections and mean energies increase as one moves from ≈100deg. to ≈170deg. similar to those for fission or evaporation-like emission. Most characteristics mimic those observed for4He, but the cross sections are smaller by a factor of as ≈1/300 for each reaction studied. A semiclassical analysis has been used to estimate the effective barriers to emission and root-mean-square spins of the emitters.
