34 | // Short description: The G4QEnvironment class corresponds to the nuclear |
---|
35 | // environment, containing excited nucleons or nuclear clusters |
---|
36 | // (G4Quasmons). In the constructer the nucleus (G4QNucleus) is clusterized |
---|
37 | // and then the projectile hadron (or hadrons) can create one (or a few) |
---|
38 | // Quasmons, which are fragmented by the Fragment member function. As a |
---|
39 | // result a vector of G4QHadrons is created, which can include the residual |
---|
40 | // nucleus in the ground state. |
