    In fact, in ordert o get deuteron interactions, one should use a version
    of FLUKA linked with a nucleus-nucleus interaction model, like RQMD (see
    the ldpmqmd script in $FLPRO/flutil), but the energy that you require is
    too low. In principle this is should be accessed through the BME model
    that is in preparation and not yet fully available.

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?
