// History: first implementation, based on object model of
// 2nd December 1995, G.Cosmo
// ------------ G4MuIonisation physics process ------------
// by Laszlo Urban, September 1997
// ------------------------------------------------------------
// It is the implementation of the NEW IONISATION
// PROCESS. ( delta rays + continuous energy loss)
// It calculates the ionisation for muons.
