// History: first implementation, based on object model of
// 2nd December 1995, G.Cosmo
// ---------- G4hEnergyLoss physics process -----------
// by Laszlo Urban, 30 May 1997
//
// ************************************************************
// It is the first implementation of the NEW UNIFIED ENERGY LOSS PROCESS.
// It calculates the continuous energy loss for charged hadrons.
// Processes giving contribution to the continuous loss :
// ionisation (= cont.ion.loss + delta ray production)
// can be added more easily ..........
// This class creates static proton/antiproton dE/dx and range tables ,
// which tables can be used by other processes.
// The energy loss for other charged hadrons is calculated from the p/pbar
// tables with scaled kinetic energy.
//
// 7/10/98 L.Urban some bugs fixed + some cleanup
// 22/10/98 L.Urban cleanup
// 02/02/99 L.Urban several bugs fixed
// 31/03/00 V.Ivanchenko rename to lowenergy as G4hLowEnergyLoss.hh
// 09/08/00 V.Ivanchenko remove GetContinuousStepLimit and IsApplicable
// 23/11/01 V.Ivanchenko Move static member-functions from header to source
// 22/01/03 V.Ivanchenko Cuts per region
// 18/04/03 V.Ivanchenko Make dRoverRange protected
//
// 31 Jul 2008 MGP Short term supply of energy loss of hadrons through clone of
// former G4hLowEnergyLoss (with some initial cleaning)
// To be replaced by reworked class to deal with condensed/discrete
// issues properly
