// Class 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. The scale of energy/momentum
|
|
// bins is natural logarithmic.
|
|
//
|
|
// History:
|
|
// 27 Apr. 1999, M.G. Pia: Created, copying from G4PhysicsLogVector
|
|
// 11 Nov. 2000, H.Kurashige : Use STL vector for dataVector and binVector
|
|
// 16 Aug. 2011 H.Kurashige : Move dBin, baseBin to the base class
