31	// File name: G4LowEnergyIonisation
32	//
33	// Author: Alessandra Forti, Vladimir Ivanchenko
34	//
35	// Creation date: March 1999
36	//
37	// Modifications:
38	// - 11.04.2000 VL
39	// Changing use of float and G4float casts to G4double casts
40	// because of problems with optimisation (bug ?)
41	// 10.04.2000 VL
42	// - Correcting Fluorescence transition probabilities in order to take into account
43	// non-radiative transitions. No Auger electron simulated yet: energy is locally deposited.
44	// 10.04.2000 VL
45	// - Correction of incident electron final momentum direction
46	// 07.04.2000 VL+LU
47	// - First implementation of continuous energy loss
48	// 22.03.2000 VL
49	// - 1 bug corrected in SelectRandomAtom method (units)
50	// 17.02.2000 Veronique Lefebure
51	// - 5 bugs corrected:
52	// *in Fluorescence, 2 bugs affecting
53	// . localEnergyDeposition and
54	// . number of emitted photons that was then always 1 less
55	// *in EnergySampling method:
56	// . expon = Parms[13]+1; (instead of uncorrect -1)
57	// . rejection /= Parms[6];(instead of uncorrect Parms[7])
58	// . Parms[6] is apparently corrupted in the data file (often = 0)
59	// -->Compute normalisation into local variable rejectionMax
60	// and use rejectionMax in stead of Parms[6]
61	//
