Methods of Transport Theory

Monte Carlo Eigenvalue Calculations of Fast Critical Assenibiies Using VIM-1, Leo B. 

Benchmark calculations of GOBIVA and JEZEBEL have been made in order to compare results with more conventional multigroup Monte Carlo and calculations reported in the literature. As can be seen in Table I, these calculations are in agreement with the consensus of results obtained using other codes with ostensibly the same ENDF/B cross-section sets. 

VlM-1 uses detailed angular distributions, prepared in the form of cumulative distribution functions of CM scattering angle at energy grids tailored to the needs of each Isotope, and uses a discrete level treatment of

The mobility is calculated by applying the variational method of transport theory, which gives the following expression for the electrical conductivity (which can be obtained by changing the appropriate expression for metals to the case of nondegenerate semiconductors) ...
