The approximation that

      1. Masses of the produced leptons are negligible
      2. Energy of incoming anti electron neutrino is by far higher
         than the electron mass.

     y = 1 - E_{l^{-1}}/E_{\bar{\nu_e}}

isValidParticle
```
public boolean isValidParticle(Particle p)

Checking the particle kind involved with a given interaction. Only electron neutrino is allowed to be involved with the Glashow resonance in the medium. This is the overriden method from Interactions.java

calculateCrossSectionAsPerNucleon
```
public void calculateCrossSectionAsPerNucleon()
```
Calculate the differential cross section as the one per nucleon. for instance in the case of ice, the number of electrons per nuclei is approximately (1 x 8 + 2 x1) - corresponding to H_2 0 !! -- is multiplied to the cross section.

calculateCrossSectionAsPerElectron
```
public void calculateCrossSectionAsPerElectron()
```
Calculate the differential cross section as the one per electron. This is simple - because the Glashow resonance is subject to electron.

setIncidentParticleEnergy

public void setIncidentParticleEnergy(double energy)

        Set The incident particle energy [GeV].
        The default value has been given by the constructor
        Interactions( ) with p.getEnergy( ) where p is 
        the Particle class. You might want to set, however,
        a different value such as 
        logE = logEnergyMinimum + deltaLogE*ilogE
        where ilogE is i'th index of the logEnergyMatrix
        in the Particle class p. This method provides you
        with a way to put the incident particle energy.
