dear users,
i would like to know that the energy loss of kr-84 heavy ions with
20MeV/n in 5cm air thickness could be around 1GeV? in *.out file i
have noticed that;
1.6783E+00 (100.%) GeV available per beam particle divided into
Prompt radiation Radioactive decays
1.5394E-01 ( 9.2%) 0.0000E+00 ( 0.0%) GeV hadron and muon dE/dx
0.0000E+00 ( 0.0%) 0.0000E+00 ( 0.0%) GeV electro-magnetic showers
0.0000E+00 ( 0.0%) 0.0000E+00 ( 0.0%) GeV nuclear recoils and
heavy fragments
0.0000E+00 ( 0.0%) 0.0000E+00 ( 0.0%) GeV particles below threshold
0.0000E+00 ( 0.0%) 0.0000E+00 ( 0.0%) GeV residual excitation energy
0.0000E+00 ( 0.0%) 0.0000E+00 ( 0.0%) GeV low energy neutrons
1.5244E+00 (90.8%) 0.0000E+00 ( 0.0%) GeV particles escaping the system
0.0000E+00 ( 0.0%) 0.0000E+00 ( 0.0%) GeV particles discarded
0.0000E+00 ( 0.0%) 0.0000E+00 ( 0.0%) GeV particles out of time limit
2.9104E-15 ( 0.0%) GeV missing
by the way, i am following the same steps given in battistoni's
example to calculate boundary crossing energies. it says to me average
1524MeV per 1675MeV heavy ions leaves from 5cm air.
could that be possible? thanks in advance.
ciao
