//  G4MuonMinusCaptureAtRest physics process
//  Larry Felawka (TRIUMF) and Art Olin (TRIUMF) April 1998
//---------------------------------------------------------------------
//
// Class Description:
//
// Process for nuclear capture of mu- at rest takes into account Fermi 
// model of muon capture in compounds, simplified EM cascade model, muon 
// decay from K-shell, and muon nucleus reaction. 

//
// Modifications: 
// 18/08/2000  V.Ivanchenko Update description, new method to simulate capture
// 12/12/2003  H.P.Wellisch Completly rewrite mu-nuclear part
// 17/05/2006  V.Ivanchenko Cleanup
// 14/11/2006  V.Ivanchenko Remove implementation of GetPhysicsInteractionLength
//
