The ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$${+}^{12}$C reaction at an incident energy E/A of 38 MeV has been investigated experimentally. Singles energy spectra and the angular distribution of reaction residues having 3≤Z≤9 were measured. A small low-energy cutoff in the spectra combined with measurements at large angles (up to 70°) allowed a study of the systematics involved in the production of low-energy reaction residues. A target-related origin is proposed for these yields. Cascade model calculations are presented which support this hypothesis.
