caveat

public java.lang.String caveat(Composition comp,
                               double e0)

compute

public abstract double compute(Composition comp,
                               double e0)

Computes the electron range using the current algorithm. To compute the range of an electron in a Material divide the results by Material.getDensity().

Parameters:

comp - The composition

e0 - The beam energy

Returns:

The result is in meters * (kg/meter^3)

compute

public double compute(Composition comp,
                      AtomicShell shell,
                      double e0)

Computes the electron range for an electron of incident energy e0 until it drops below the edge energy for the specified shell in the specified material.

Parameters:

comp - The material's composition

shell - The shell defining an edge energy

e0 - The incident beam energy

Returns:

The range in meters * (kg/meter^3)
