Inclusive spectra of protons and α particles resulting from the interaction between 30.0-MeV protons and the 209 Bi nucleus are investigated. Double differential and integral cross sections for the (p, x p) and (p, x α) reactions are obtained and total partial cross sections for these reactions are subsequently determined. The experimental spectra are analyzed using a modified version of the exciton model of preequilibrium decay and the PRECO-2006 code. Contributions from the compound and direct mechanisms to the formation of integral cross sections are calculated.
