// Description:
|
|
// A physics ordered free vector inherits from G4PhysicsVector which
|
|
// has values of energy-loss, cross-section, and other physics values
|
|
// of a particle in matter in a given range of the energy, momentum,
|
|
// etc.). In addition, the ordered free vector provides a method for
|
|
// the user to insert energy/value pairs in sequence. Methods to
|
|
// Retrieve the Max and Min energies and values from the vector are
|
|
// also provided.
