34 // ---------- G4hEnergyLoss physics process -----------
35 // by Laszlo Urban, 30 May 1997
36 //
37 // **************************************************************
38 // It is the first implementation of the NEW UNIFIED ENERGY LOSS PROCESS.
39 // It calculates the energy loss of charged hadrons.
40 // **************************************************************
41 //
42 // 7/10/98 bug fixes + some cleanup , L.Urban
43 // 22/10/98 cleanup , L.Urban
44 // 07/12/98 works for ions as well+ bug corrected, L.Urban
45 // 02/02/99 several bugs fixed, L.Urban
46 // 31/03/00 rename to lowenergy as G4hRDEnergyLoss.cc V.Ivanchenko
47 // 05/11/00 new method to calculate particle ranges
48 // 10/05/01 V.Ivanchenko Clean up againist Linux compilation with -Wall
49 // 23/11/01 V.Ivanchenko Move static member-functions from header to source
50 // 28/10/02 V.Ivanchenko Optimal binning for dE/dx
51 // 21/01/03 V.Ivanchenko Cut per region
52 // 23/01/03 V.Ivanchenko Fix in table build
53 
54 // 31 Jul 2008 MGP Short term supply of energy loss of hadrons through clone of
55 // former G4hLowEnergyLoss (with some initial cleaning)
56 // To be replaced by reworked class to deal with condensed/discrete
57 // issues properly
58 
59 // 25 Nov 2010 MGP Added some protections for FPE (mostly division by 0)
60 // The whole energy loss domain would profit from a design iteration
61 
62 // 20 Jun 2011 MGP Corrected some compilation warnings. The whole class will be heavily refactored anyway.
