Interaction of Yttrium with Protons of Energy between 60 and 240 Mev

Abstract
Absolute cross sections are reported for a number of nuclides produced by the interaction with yttrium of protons of 60, 100, 150, 180, and 240 Mev. At low energies the yields can be accounted for by direct interaction or knock-on processes. At higher energies the knock-on cascade model together with evaporation appears to explain the observed yields.
