1. Theoretical Calculations
Relativistic charged particles lose energy in matter primarily by ionization. The mean rate of energy loss is given by the Bethe_Bloch equation,
-
= 0.307075 MeV
=61 keV
=0.033
For example, for incident particle Ce-140 and target U-238, we have following results for energy loss
Density of Uranium is 19.1 [1]
-
The half length is the distance needed to reduce the intensity in half
Time t=
= nsec
