Results:yield of prompt neutrons as a function of angle relative to the
direction of light fission fragment in the lab. system
• Introduction of anisotropy with A2 = 0.04 into the calculationimproves agreement with obtained experimental data. At that, thereis some surplus of measured yield over calculated at angles near 900.

CHALLENGES
Develop evaluation methodology that combines
rigid models (highly correlated) with shape
experimental data
Derive evaluations that reproduce the differential
data and give reasonable RR and dosimetry
performance
Impact of new evaluations on benchmarks
