Nucleon-induced secondaries: A review and future experimental developments

We discuss the experimental situation of nucleon-induced reactions. Motivated by important current technological applications such as single event upsets (SEU) in microelectronic devices and particle-beam radiotherapy, we focus on light elements and beam energies below 250 MeV. We review the data from proton- and neutron-induced reactions obtained at UC Davis and elsewhere in the last 2 decades. Despite the large compilation of data (mainly inclusive spectra of light ions), we point out the scarcity of recoil data. We emphasize the fact that recoil nuclei contribute a significant part of the secondary radiation which is a major source of SEUs in devices, and of importance for radiation-related calculations. We discuss a new program under development, in which we measure recoil spectra using reverse kinematics. We discuss results from a recent experiment of ${}^1\mathrm{H}{(}^{28}\mathrm{Si}\mathrm{,A)x}$ at 80 MeV/nucleon performed at the NSCL at Michigan State University. The preliminary data are compared well with a cascade-statistical reaction model (NUSPA).
