Abstract
Spallation-neutron fluence distributions and integral yields for protons of Ep=300-590 MeV incident on thick Pb/Bi targets immersed in a water bath have been determined. The results constitute a data-base pertinent to a well-defined, representative configuration for practicable, high-intensity spallation neutron sources at these intermediate beam energies. They include neutron-fluence distributions based on Au and Mn reaction rates around a thick Pb/Bi target at Ep=300, 420 and 590 MeV and total n/p values at 420 and 590 MeV, respectively. The latter agree well with previously-measured values, but are of higher precision. Such a database permits accurate benchmarking and detailed inter-comparison of particle-transport-code predictions.
