/*!
* LEMuSRMUONIUM class defines the muonium formation process in the carbon foil according
* to yields from Gonin's paper Sci. Rev. Instrum. 65 (3), 648-652 (1994).
*
* \image html yields3.gif The muonium formation yields.
*
* The main parameters are the thickness of the foil and the energy of the muon. For a given
* energy, a corresponding proportion of the muons will be converted into muonium.
* Concretely, the muon will be killed and replace by a muonium with same properties of time,
* energy, momentum, position etc.
*
* This process is executed at the end of a step, i.e. the muon is converted into muonium after
* flying through the carbon foil.
*cf. yields.h, gonin.cc.
