Under this directory, you will find two methods to calculate the energy spectra of ($\alpha$, n) interaction in concrete. The first one was originally wriiten by Weihe Zeng and i rewrited it following the conventions. While the latter Geant4 simulation is achieved by myself.

1. Although the numerous calculations have been achieved by Weihe Zeng, he paid little attention to the reusability, which leads to inconvenience.
2. When i rewrited it, i realized that it is not achievable since the libraries were generated manually 😭 !!!!! Which made the management and updates more complicated!
3. Well, here comes a good news :happy:! A literature said that Geant4 can be used to simulate this process if you manifest the libraries accurately !
