I have given the two most obvious cases, but the whole thing is more
complicated. There are intermediate cases where the "Useful Energy"
is kinetic + one rest mass.
Anyway, the fact that a particle escapes with no interactions is irrelevant:
the useful energy is a measure of the particle potential energy deposition,
not of the deposition that actually happens.
