public class MuDecayMatrix extends java.lang.Object
Matrix of the Energy Transfer by the mu decays The matrix elements are calculated by the methods supplied by the Decay class. /------------------------------------------------------------\ logEmin | 0 0 ................................... Emin dN/dEmin | logE1 | 0 0 ............................E1dN/dE1 Emin dN/dEmin | . | |x binWidth ln(10) . | | logEmax |Emax dN/dEmax................................ Emin dN/dEmin | \------------------------------------------------------------/ The bin width and logEmin are defined in the Particle class. Actually each matrix element dN/dLogEdecay is calculated by the integral, \int dN/dY dY from logY - 0.5xbinWidth to logY + 0.5*binWidth where logY = logEdecay - logEmu. This is more accurate way than simply calculating dN/dLogEdecay. The transfer matrix to the nu-mu is acquired by the method getMuToNuMuDecayMatrix( ), that to the electron neutrinos by getMuToNuEMatrix( ) that to the other charged leptons such as e by getMuToEDecayMatrix( )
