APPROXIMATE FORMULAE FOR THE CALCULATION OF EFFECTIVE RESONANCE INTEGRALS IN THE STATISTICAL REGION
Technical Report
·
OSTI ID:4760067
Approximate formulae are given for calculating values of the function J( xi , BETA ) averaged over the Porter-Thomas distribution of reduced neutron widths, so that effective resonance integrals can be calculated in the statistical region. A method of error correction is suggested. In the case of infinitely dilute resonance integrals, averaging over the Porter-Thomas distribution and integrntion over energy can be carried out explicitly, if it is assumed that in the statistical region resonances have a uniform spacing equal to the mean of the stntistical distribution of spacing.
