TL;DR: In this paper, the spectral shapes for the evaporative component are compared with statistical model calculations, and information is obtained concerning the effective barriers to emission, as well as Fission angular distributions and cross sections.

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.

Angular momentum transfer in 12C-, 20Ne- and 40Ar-induced fission
TL;DR: In this article, angular momentum transfer in a variety of 12C-, 20Ne-and 40Ar-induced fission reactions has been investigated using γ-ray multiplicity techniques.

Alpha emission in coincidence with fission-like fragments from Cl+Ag reactions at 10 MeV/n
TL;DR: In this article, energy and angular correlations between alpha particles and fission-like fragments in the reaction of 35Cl+Ag at 10 MeV/n have been measured and the coincident yield is dominated by two mechanisms: sequential emission from both fragments and alpha emission from the composite system prior to scission.

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.

Damped Heavy-Ion Collisions
W. U. Schröder,J.R. Huizenga +1 more
TL;DR: Macroscopic and microscopic models of heavy-ion nuclear reactions are discussed in this paper, where the relationship of different experimental parameters are considered. But they do not consider the effects of different types of nuclear reactions.

On angular distributions in compound nucleus processes
TL;DR: The angular anisotropy of particles emitted in compound processes is due to restrictions on the directions of their angular moments, which are imposed by the angular momentum distribution of the residual nucleus.

Pre-equilibrium alpha emission accompanying deep-inelastic 16 O+ 58 Ni collisions
H. Ho,R. Albrecht,W. Dünnweber,G. Graw,S. G. Steadman,J.P. Wurm,D. Disdier,V. Rauch,F. Scheibling +8 more
TL;DR: In this paper, a hot spot is proposed to resolve the conflict of coexisting statistical and direct features of the pre-equilibrium emission, and a local temperature ofT−3.5 MeV is deduced which agrees well with the shape of the α spectra.

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.
