public class InteractionsMatrix
extends java.lang.Object
implements java.io.Serializable

    Matrix of the Energy Transfer by particle Interactions.
    The matrix elements are calculated by the methods supplied
    by the Interaction class.

The bin width and logEmin are defined in the Particle class.

Actually each matrix element dSigma/dLogE is calculated by the integral,
\int dSigma/dY dY from logY - 0.5xbinWidth to logY + 0.5*binWidth where
logY = logEproduced - logEincoming. This is more accurate way than simply
calculating dSigma/dLogE.

The transfer matrix of the recolied lepton energy (1-y)*Eincoming 
is acquired by the method getLeptonTransferMatrix( )
while the energy of the transfered matrix for the counter current 
y*Eincoming is obtained by getTransferMatrix( ).
