// Description:
|
|
// A physics vector 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.
|
|
// This class serves as the base class for a vector having various
|
|
// energy scale, for example like 'log', 'linear', 'free', etc.
