// Author:       Yoshihide Sato - November 2023
//
// Description:  Variant of G4IonQMDPhysics in which G4LightIonQMDReaction
//               is used in the interval [30 MeV, 510 MeV]/nucleon
//               (G4BinaryLightIonReaction is used below 40 MeV/nucleon,
//                and G4QMDReaction is used in the interval
//                [500 MeV, 6 GeV]/nucleon).
