Thank you for information.
But I would like to know which is the cross section of Deuteron scattering
on carbon included in Fluka.
If the driver to print it is still missing, how can I tell what the cross
section is?
The authors of fluka which somehow included the cross section inside a
library, could please tell me the
table of this cross section: millibar vs energy?
Thank you again
Best Regards
Francesco
