Decay of primary fission fragments (FF) can be described by the statistical theory of Hauser-Feshbach (HF). However, such calculations can have a large uncertainty due to a not so well defined initial configuration of excited fragments. We present prompt neutron multiplicities and isomer productions calculated from FF, TKE and TXE distributions estimated by several methods.
