Deriving Prompt Neutron Emission from Fission Product Yields

A natural connection exists between the fission product yields and the prompt neutron emission. The average neutron emission for a fission of a particular nucleus (nu) over bar is typically known to a very high level of certainty. In addition, the average neutron emission as a function of the fragment mass (nu) over bar (A) also provides a connection between not only average quantities, such as (nu) over bar, but also the prompt neutron emission distribution. In this way, one can utilize established prompt neutron data as a constraint on fission product yields.
