26 // Class Description
27 // Container of LEND (Low Energy Nuclear Data) target (nucleus)
28 // LEND is Geant4 interface for GIDI (General Interaction Data Interface)
29 // which gives a discription of nuclear and atomic reactions, such as
30 // Binary collision cross sections
31 // Particle number multiplicity distributions of reaction products
32 // Energy and angular distributions of reaction products
33 // Derived calculational constants
34 // GIDI is developped at Lawrence Livermore National Laboratory
35 // Class Description - End
