I am a former Senior Manager of Software Development at Amazon, where I managed the development of the amazon.com content selection and delivery software (i.e. Amabot). I also invented, designed, and developed the engineering of Amazon.com's behaviorial-targeted third-party display advertising product.
Angular neutron flux Amount of neutron track length in a differential volume about , associated with particles of a differential energy in about , moving in a differential solid angle in about , at time .
Scalar neutron flux Amount of neutron track length in a differential volume about , associated with particles of a differential energy in about , at time .
Average number of neutrons produced per fission (e.g., 2.43 for U-235).[1]
Probability density function for neutrons of exit energy from all neutrons produced by fission
Probability density function for neutrons of exit energy from all neutrons produced by delayed neutron precursors
Macroscopic total cross section, which includes all possible interactions
Macroscopic fission cross section, which includes all fission interactions in about
Double differential scattering cross section Characterizes scattering of a neutron from an incident energy in and direction in to a final energy and direction .
