Figures of neutron reproduction factors (η) for 81 fissionable nuclides in JENDL-5 are available in this page. The reproduction factors were calculated from JENDL-5 pointwise files at 0 and 300(K) by { η(E) = νave.(E) σf (E) / σa(E) }. "Continuous" is a link to the figure of continuous energy distribution, and "Av70" is a link to 70-group averaged energy distribution.
