  In braneworld collisions fermions originally localised on one brane can be
transferred to another brane, or to a space-time boundary. By modelling branes
as scalar field kinks we bounce them off boundaries and study resulting effects
according to a braneworld observer. Extending on our previous work, we
numerically compute the spectrum of excitations of fermion modes localised on
the brane and boundary, in terms of the momentum $k$ along the brane
dimensions. We find that the spectrum depends strongly on collision velocity
and fermion-scalar coupling. Also, high-momentum modes tend to ``fall off'' the
kinks and become delocalised radiation.
