Inclusive cross sections,p(0.8 GeV)+A→p+X, up to theLi6elastic limit

Results of experimental measurements on protons produced at 100° and 158° from ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$, ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$, and ${}_{}{}^{181}{}_{}{}^{}\mathrm{Ta}$ targets are presented and compared with the mass number ($A$), angular ($\theta$), and momentum dependence of "quasi-two-body scaling."
