Isotopic production cross sections in proton-nucleus collisions at 200 MeV

Intermediate-mass fragments from the interaction of Al-27, Co-59, and Au-197 with 200-MeV protons were measured in an angular range from 20(degrees) to 120(degrees) in the laboratory system. The fragments, ranging from isotopes of helium up to isotopes of carbon, were isotopically resolved. Double-differential cross sections, energy-differential cross sections, and total cross sections were extracted.
