I am interested in the (g,p) reaction with Zn-68, leading to Cu-67.
Fluka (2021) successfully calculates the yield of Cu-67 in the energy range from 10 to 30 MeV.
However, the yield is more than a factor of two lower than measured yields.
I have extracted the (g,p) cross section using a MC “measurement” and it is more than a factor of two smaller than the EXFOR value.
Can someone comment on the estimated uncertainty of the photoproton yield predicted by Fluka?
Thanks,
Carl Ross
