FLUKA_Spectrum_Source_18MeV_pH2O18.dat:
=======================================
Source spectrum of a 18 MeV proton beam hitting a water target enriched with
97% of O-18 obtained with FLUKA version FLUKA2011.2x.3.

MCNP6_Spectrum_Source_18MeV_pH2O18.dat:
=======================================
Source spectrum of a 18 MeV proton beam hitting a water target enriched with
97% of O-18 obtained with MCNP version MCNP6.2.

The data is organized in the following fields:

Emin [MeV]:
Lower bin border of energy group in MeV

Emax [MeV]:
Upper bin border of energy group in MeV

Diff. Yield  
Neutr/MeV/pr:
Differential neutron yield per primary proton (dN/dE/primary) in
Neutrons/MeV/primary (multiply with 6.242E12 prot/s to normalize to 1 microA of
proton current)

Unc.:
Stat. uncertainty on diff. yield in Neutrons/MeV/primary
(multiply with 6.242E12 prot/s to normalize to 1 microA of proton current)

Int. Yield
Neutr/prim:
Bin-integrated neutron yield per primary proton  (dN/dE/primary)*(Emax-Emin) in
Neutron/primary (multiply with 6.242E12 prot/s to normalize to 1 microA of
proton current)

Unc.:
Stat. uncertainty on bin-integrated yield in Neutrons/primary
(multiply with 6.242E12 prot/s to normalize to 1 microA of proton current)
