31 // File name: G4HadronStoppingProcess
32 //
33 // Author V.Ivanchenko 21 April 2012 on base of G4MuonMinusCaptureAtRest
34 //
35 //
36 // Class Description:
37 //
38 // Base process class for nuclear capture of negatively charged particles
39 //
40 // Modifications:
41 // 20120928 M. Kelsey -- Add GetMeanLifeTime() here, instead of in base.
42 // 20121004 K. Genser -- defined two argument constructor with defaults
43 // 20121016 K. Genser -- Reverting to use one argument c'tor
44 // 20140818 K. Genser -- Labeled tracks using G4PhysicsModelCatalog
