/*!
|
|
* LEMuSRMUONIUMScatt class defines the muonium scattering process. It is a very basic model
|
|
* since we assume the muonium loose its electron as soon as it enters a material
|
|
* (other than vauum).
|
|
*
|
|
* Moreover, the spin precession of the muonium in flight is also implemented in this clss.
