Question about low energy limit of light ions

    Hi everybody,

I'm working on MC simulations of the T(d,\alpha)n reaction using the Time
Correlated Associated Particle Method (TCAP). We'll use a 150 keV deuteron
beam and a 500 ug/cm^2 (=3D 0.173 um) Ti(T) target tilted by 45=B0 relative to
the beam.
The alpha particle will have an energy of 3.5 MeV and should be detected in
a Si detector.
The simulation should mainly serve to understand angular straggling of
deuteron and alpha particle in the Ti target.

On page 8 (section 1.2.3) in the FLUKA manual I found a list of transport
limits for primary and secondary particles.
Can 150 keV deuterons be treated as charged hadrons (then they would be
within the limits) or rather as heavy ions (then the limits are too high?)?
The Moliere straggling is taken into account in FLUKA according section
1.2.1.4 of the manual. This would be perfect.

Thank you for your help.

    Yours sincerely, Martin Erhard
