FISSION FRAGMENT ANGULAR ANISOTROPIES AND INERTIA PARAMETERS
An analysis of selected fission fragment angular distributions from helium-ion induced fission is made using an exact theoretical expression. Theoretical anisotropies obtained with the transition state model are compared with their corresponding values deduced from the statistical scission model. The nuclear moment of inertia extracted from the model calculations are compared with their est...

متن کاملLimitations to presaddle neutron emission from fission-fragment charge distributions.
The e8'ect of including mass-asymmetry dependent 6ssion delay times into the statistical model has been investigated. The shape of the predicted charge distribution of fission fragments is found to be very sensitive to the magnitude and mass-asymmetry dependence of these delay times. Measured mass-asymmetry dependent prefission neutron multiplicities were fit with calculated presaddle values by...
متن کاملEffects of Neutron Emission on Fragment Mass and Kinetic Energy Distribution from Thermal Neutron-Induced Fission of 235U
The mass and kinetic energy distribution of nuclear fragments from thermal neutroninduced fission of U(nth, f ) have been studied using a Monte-Carlo simulation. Besides reproducing the pronounced broadening in the standard deviation of the kinetic energy at the final fragment mass number around m = 109, our simulation also produces a second broadening around m = 125. These results are in good ...
متن کاملNeutron-induced deuteron production from light nuclei at 800 MeV
The deuteron sepctra from {n,d) reactions at 800 MeV near 0' are characterized by a high energy quasielastic scattering peak, and at lower momentum, a quasifree scattering peak. The ratio of the quasifree to quasielastic cross sections is approximately 10:1.Both cross sections exhibit an A '" mass dependence over the range of target nuclei studied. Comparisons are made with corresponding proton...
