    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
