A new 121 group (100 neutron group, 21 gamma group) coupled cross section library with anisotropic scattering has been generated at IGCAR for 25 nuclides by using the 1985 version of NJOY code system. The basic data used are ENDF/B-IV for neutrons and DLC-99 for photons. A set of six neutron source benchmarks, one gamma source benchmark and one gamma production benchmark has been used in validating this new library. Of these, the first six are computational benchmarks and the last two are experimental benchmarks. Reasonably good predictions have been obtained with this new set relative to the reference solutions. Thus, capability has been developed at IGCAR for generating new multigroup cross section libraries for shielding applications.
