## The Birk’s law

When charged particle deposited energy in the liquid scintillator, the energy will be transferred to the primary fluor and emits scintillation light. However they are not proportional. The problem is the birks law.

Today I found an article and they write an rountine to calculate it.. very nice!

And it can be downloaded from  http://www.cpc.cs.qub.ac.uk

Good place.

Besides, I will check if I can find a way to write article with MarkDown, and upload picture easily.

Now it seems work!

#include <iostream>;
int main(int argc, char *argv[]) {
return 0;
}


test:

(1)

[
\sin 2
]

(2)

[
\sin 2
]
