PRESENT STATUS OF RESEARCH ON INTERMEDIAT E-ENERGY NUCLEAR-DATA

Present status of a research on intermediate energy nuclear data, whic h are required for various applications, are reported. As an important foundation for data evaluation at intermediate energy region, nuclear reaction theories and models such as the preequilibrium model, intran uclear cascade model, quantum molecular dynamics, optical model potent ial and fission model, are reviewed. The model calculation codes are h aving been developed based on these theories and models. Status of the se codes and results of a few benchmark tests are also described as we ll as the status of production of evaluated intermediate energy nuclea r data files and improvement of hadron transport theories.
