// ------------ G4LowEnergyIonisation physics process --------
// by Michel Maire, April 1996
// ---------- G4LowEnergyIonisation low energy modifications -----------
// by Alessandra Forti May 1999
// **************************************************************
// 17.02.2000 Veronique Lefebure
// - 5 bugs corrected:
// *in Fluorescence, 2 bugs affecting
// . localEnergyDeposition and
// . number of emitted photons that was then always 1 less
// *in EnergySampling method:
// . expon = Parms[13]+1; (instead of uncorrect -1)
// . rejection /= Parms[6];(instead of uncorrect Parms[7])
// . Parms[6] is apparently corrupted in the data file (often = 0)
// -->Compute normalisation into local variable rejectionMax
// and use rejectionMax in stead of Parms[6]
//
// Added Livermore data table construction methods A. Forti
// Modified BuildMeanFreePath to read new data tables A. Forti
// Added EnergySampling method A. Forti
