The (n,p), (n,d), and (n, alpha ) reactions induced by 14.6 Mev neutrons in CsI(Tl) scintillation crystals were observed. Pulse shape discrimination was used to distinguish the various particles, permitting an energy spectrum for each to be obtained. The proton and alpha particle spectra were analyzed from the point of view of the statistical theory of nuclear reactions, but there are left over substantial components that must be attributed to direct interactions. The direct component for protons is estimated to be at least 45%, amd for alpha particles to be at least 38%. Absolute cross sections have been obtained by the method of tagging the neutron beam by its associated particles; the averages for Cs and I are found to be re p-terphenyl (n,p) = 8 450 deg C in a 1 mb, re p- terphenyl (n,d) = 1.2 450 deg C in a 0.2 mb, and re p-terphenyl (n, alpha ) = 1.8 450 deg C in a 0.2 mb.
