Hi,
I'm trying to find the range of α-particles in silicon; I can work out the stopping power, [itex]\frac{dE}{dx}[/itex], but the reference I'm using then states that I need to integrate it as follows:
[itex]R=\int_T^0 ([/itex]-[itex]\frac{dE}{dx} ) ^{-1} dE[/itex]
The thing is, I'm not sure as to how to even start this integration, can anyone help?
I can actually look up the value using the page below to calculate it, but I'd like to check it by doing it myself.
http://physics.nist.gov/PhysRefData/Star/Text/ASTAR.html
Also this page gives the units of range in g/cm2, can anyone explain why it's this and not just cm or m? I've seen in other places where g/cm2 and cm seem to be interchangeable, so if it gives the range as 7.375x 10-03g/cm2, can I just use it as 7.375x 10-03cm?
Many thanks!
