【 摘 要 】

Momentum is a neutron multiplicity analysis software package that calculates a variety of parameters associated with Feynman histograms. While most of these parameters are documented in Cifarelli and Smith-Nelson, there are some parameters which are not. Most prominent of these are the uncertainties in the standard moments, and this paper will explicitly document these parameters. This paper will also document the higher-order Y_n parameters and their associated ??_n functions because they may be useful for future applications. The generation of what is referred to as Feynman histograms is not explained here.
