Fission product yield sublibrary
The fission product yield sublibrary provides the evaluated nuclear data on neutron-induced and spontaneous fission yields for 31 and 10 nuclides, respectively. The data were compiled with the decay data sublibrary to keep the consistency between the number of nuclides contained in the decay data sublibrary and fission product yield sublibrary.

[History]
Dec. 2021: First release (archive file).

Feb. 2022: Sublibrary and library version numbers were incorrect. The projectile mass for Am-242m was also incorrect. Fixed in update 2 (upd-2) on Feb. 16. (archive file).

Jul. 2022: Identifiers of fission product yield (ZAFP) for 14 MeV neutron FPY data were given incorrectly. Fixed in update 8 (upd-8) on Jul. 13.

Feb. 2023:Cumulative yields (CY) of original JENDL-5 were evaluated by letting all unstable nuclei decay. Alternatively, CY calculated by letting nulcei with T1/2 < 1000 y decay were made available.
