Dear Fluka users,
It's a long time ago that I have not used fluka.
I want to calculate the activity of 64Cu induced by 18 MeV protn on a
Ni64 target (360 micron)
thickness.
I use the RESNUCLE card in order to get the production of Cu64.
The result is 4.7E-6 Atom/p ---> A = 4.33E-5 mCi/(MicroA.h).
The results is far below what I'm expecting (1000 times higher).
Is my input file correct ?
If yes where is the problem ?
Thanks in advance
Yann
