I'm looking for gamma lines such as:
1.78 MeV from 27Al(n,g)28Al, half-life 2.3 m
0.847, 1.811 and 2.113 MeV from 55Mn(n,g)56Mn, half-life 2.6 h
1.369 and 2.754 MeV from 23Na(n,g)24Na, half-life 15 h
0.479 and 0.686 MeV from 186W(n,g)187W, half-life 23.9 h
0.511 and 0.564 MeV from 121Sb(n,g)122Sb, half-life 28 d
1.346 MeV from 63Cu(n,g)64Cu as well as 65Cu(g,n)64Cu, half-life 12.7 h
0.511 MeV from 63Cu(g,n)62Cu, half-life 9.7 m
1.378 and 1.92 MeV from 58Ni(g,n)57Ni, half-life 36 h
Thanks very much.

Can you be a little bit more explicit on what you really would like to
If you mean delayed emission of neutrons:
it is true that we do not produce them in FLUKA, but there is
no particular difficulty behind that. Their inclusion is part of our
project of improvement of the neutron library and we hope to achieve that
goal, soon or later.
If you are instead interested in gamma emission after neutron capture,
then this is already included in FLUKA.
