Dear Chris
the models will fail sooner rather than later for neutrons below 20 MeV,
because, while they could do things not completely nonsense down to
~10 MeV, below they cannot be used and even less in the resonance,
epithermal and capture regions.
If your issue is to compute offline residual nuclei production cross
sections, you can use the data in whichever endf format evaluations which
contains the relevant rubidium isotopes. If you need them in a
cascade-like full-fledged simulation you have to tell Fluka which other
element to use in place of Rubidium below 20 MeV, otherwise the code will
not run. Of course if it is of importance for you we could add rubidium to
the low energy neutron library in a next release (I have alreayd another
request for it)
Ciao

Am I correct in my assumption that I can still calculate the residual nuclei for such elements produced by neutrons above 20 MeV based on FLUKA's production model?
