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.
