Helium production cross sections
Discrepancies both for measured as well as for
calculated production cross sections

Hydrogen production cross sections
Good agreement between INCL GEMII evaporation
LAHET RAL evaporation overestimates H cross
section for all Zs and the He production for
heavy nuclei due to E dependent Coulomb
barriers The ORNL option of LAHET (no E
dependence Vc) overestimates H-production and
underestimates He FLUKA underestimates H and He
cross sections

• event wise counting of neutrons
• signals any reactions with an inelasticity gt 2 MeV
