Abstract
The probability of emitting a neutron following decay is critical in many areas of nuclear science, from understanding nucleosynethesis during the process to control of reactor power levels and nuclear waste management. As it is not always easy to measure or calculate, indirect empirical approaches have been developed to estimate the value from the decay value and the neutron separation energy S. Here, we present a new prescription incorporating also the half-life , which correlates the known data better and thus improves an estimation of when only , , and S are known. This new relation can be used to predict values for cases where the half-life is known, thus it can be useful in -process network calculations and in modeling advanced fuel cycles.
