    Hi.

    Following my query on 24th July that I couldn't find any secondaries produced by 10 MeV deuterons in nitrogen-14, I can't find any in neon-20 either.

    Is this due to the following explanation:
    "In 1992, transport of light ions (deuterons, tritons, 3He, a) was introduced, without nuclear interactions."
    which I found on page 363/405 of CERN-2005-10.pdf?

    Many thanks,
    mary

    > I started 30 MeV deuterons in N14. Deuteron threshold was 10 keV. Input file given below. I found the stars generated per beam particle to be 100% deuterons. Number of secondaries per call to usdraw was at most one, and when it happens the secondary is a deuteron. Shouldn't I expect some neutrons and gammas?
