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.

Equilibrium treatment of spin-depolarizing modes in mass asymmetric heavy-ion systems
R.P. Schmitt,Alberto J. Pacheco +1 more
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.

Angular — momentum — bearing modes in fission
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.

Equilibrium configurations of rotating charged or gravitating liquid masses with surface tension. II
TL;DR: In this article, the authors discuss in a unified manner configurations of idealized atomic nuclei, rotating liquid drops and rotating idealized astronomical masses with surface tension, and the existence of super-deformed nuclei.

Statistical emission of large fragments: A general theoretical approach
TL;DR: In this paper, a theory for the statistical emission of large fragments is developed, where a ridge line in the potential energy surface is defined which controls the decay width of the system into any two given fragments.

Tangential friction in deep-inelastic scattering of $sup 16$O from nickel
Abstract: Bombarding Ni targets with 96-MeV $^{16}\mathrm{O}$ ions, we have observed deep-inelastic groups of mass-16 and -12 reaction products with $Q$ values centered at -30 to - 35 MeV. From the multiplicity of the coincident $\ensuremath{\gamma}$ de-excitation, total fragment spins and hence, using a classical model, orbital angular momentum transfers of $12\ensuremath{\hbar}$ to $15\ensuremath{\hbar}$ are deduced. These, and at least 50% of the energy dissipation, are ascribed to tangential friction.

Angular momentum transfer in deeply inelastic collisions from exclusive sequential-fission experiments
TL;DR: In this article, the authors performed Kinematically complete experiments on the three-body exit channels in 7.5 MeV/amu /sup 208/Pb and /sup 238/U on /sup 58/Ni and/sup 90/Zr. The bulk of the events (> 99%) can be interpreted as sequential fission following deeply inelastic collisions.

(3He, xn), (3He, pxn) and (3He, fission) reactions on 206Pb between 80 and 200 MeV
TL;DR: In this article, the reactions induced in 206Pb by 3He particles having energies between 80 and 200 MeV have been studied and the results indicated that non-compound processes played an important role in the reactions.
