double	scaleFactorSigma = 1.
	Scaling for Sigma.

Detailed Description

Simulate energy loss using the Bethe-Bloch/Landau description.

Energy loss is computed using the most probable value and appropriate fluctuations from a Landau distribution. No secondaries are generated for the removed energy.
