Prescission neutron multiplicity and fission probability from Langevin dynamics of nuclear fission

Measurement of Fission Neutron Spectrum and Multiplicity using a Gamma Tag Double Time-of-flight Setup

Recent efforts have been made to improve the prompt fission neutron spectrum and nu-bar measurements for Uranium and Plutonium isotopes particularly in the keV region. A system has been designed at Rensselaer Polytechnic Institute (RPI) utilizing an array of EJ-301 liquid scintillators as well as lithium glass and plastic scintillators to experimentally determine these values. An array of BaF2 ...

Simultaneous Measurement of Fission Neutron Multiplicity and Spectrum Using a Gamma Tagging Method

Ac There is currently a need for highly accurate measurements of fission neutron multiplicity ( ̅) and spectrum for U particularly in the range of sub 1 MeV fission neutron energy. These measurements increase the accuracy of calculations used to model nuclear fission systems. Gamma tagging is a new method for accurately measuring these quantities. This method utilizes an array of gamma detectors...

The Study of Nonlinear Dynamical Systems Nuclear Fission Using Hurwitz Criterion

In this paper, the nonlinear dynamic system of equations, a type of nuclear ssion reactor is solved analytically and numerically. Considering that the direct solution of three-dimensional dynamical systems analysis and more in order to determine the stability and instability, in terms of algebraicsystems is dicult. Using certain situations in mathematics called Hurwitz criterion, Necessary and ...

The Mechanism of Nuclear Fission

On the basis of the liquid drop model of atomic nuclei, an account is given of the mechanism of nuclear fission. In particular, conclusions are drawn regarding the variation from nucleus to nucleus of the critical energy required for fission, and regarding the dependence of fission cross section fo'r a given nucleus on energy of the exciting agency. A detailed discussion of the observations is ...
