Question on Low Energy Secondary Generation

Hello,

Its my understanding that for low energy Hadronic particles (1-20 MeV), even with ParticleHP used to calculate the rate of inelastic interactions, the decay channel of the compound nucleus and the assignment of energy and direction to any secondaries generated is still determined using a high energy physics model (ie. the Precompound model, etc). Is this correct?

If so, I was curious as to what the reasoning is for using these models to generate the initial states the secondary particles, rather than using empirical data from say JENDL, on the angular distribution of these secondary particles. Or, is there a physics model where data driven secondary modeling is implemented?

Thanks,
Arthur

particleHP is data driven. Yo can find more details in the Physics Reference Manual
