Nuclear data status and needs for spallation physics investigations

The application potential of spallation facilities is widespread especially as intense neutron sources for solid state and nuclear physics, material damage studies, in medicine and radiobiology, simulation of space radiations, and nuclear technology. Nuclear data needed include total, elastic, nonelastic, and production cross sections. Particle yields are needed for source calculations. Data for operation of spallation sources include cross section for transport, dosimetry, damage energy, transmutation, and gas production. In particular high energy cross section evaluation is considered besides material damage and gas production data
