Re: FLUKA: Re: Residual nuclei
Just a further clarification on top of what Alberto wrote.
The answer to point 3 "The scoring does not distinguish between states:
they are all scored as the same isotope" should be read "The scoring does
not distinguish between ground state and isomeric state: they are all
scored as the same isotope. No scored isotope is in a state different from
the ground state or a (possible) isomeric state, since the deexcitation
routines are taking care of dissipating into particles and ultimately
photons all exciation energy"
