30 // ClassName: G4StoppingPhysics
31 //
32 // Author: Alberto Ribon
33 //
34 // Date: 27 July 2012
35 //
36 // Modified:
37 // 20120921 M. Kelsey -- Move MuonMinusCapture.hh here; replace G4MMCAtRest
38 // with new G4MuonMinusCapture.
39 // 16-Oct-2012 A. Ribon: renamed G4BertiniAndFritiofStoppingPhysics as
40 // G4StoppingPhysics.
41 // 17-Oct-2012 A. Ribon: added nuclear capture at rest of anti-nuclei with
42 // Fritof/Precompound.
