すべての実装されたインタフェース:: java.io.Serializable, Function

public class PhotoNuclearFit
extends java.lang.Object
implements Function

    The Photo Nuclear interactions
    taking place in undergound rock and ice are calculated in this subclass.

    The class variables  Particle, and Point are necessary for the methods
    described here because the cross section depends on the particle propaty
    and the medium like Z and A(atomic number).

    This class, different from PhotoNuclear.class, reads the numerical table
    generated by MakePhotoNuclearTable.java and calculate the relevant cross sections
    with numericaly interpolating the table.

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.
