32 // The particles are generated uniformly on th
33 // distribution set to a cosine law relative t

38 // is also computed. The area is needed to fix
39 // adjoint particle.
40 // At the time of the development of this clas
41 // volume surface and computation of surface w
42 // the general ray tracking technique was adop
43 // G4VSolid could be now (2009) used instead.
