Measurements of the invariant cross sections for the reaction $p\left(400\mathrm{} \mathrm{GeV}\right)+({}_{}{}^6{}_{}{}^{}\mathrm{Li}, \mathrm{B}\mathrm{e},\mathrm{C},\mathrm{A}\mathrm{l},\mathrm{C}\mathrm{u},\mathrm{T}\mathrm{a})\to (d, t, {}_{}{}^3{}_{}{}^{}\mathrm{He}, {}_{}{}^4{}_{}{}^{}\mathrm{He})+X$ at laboratory angles of 70, 90, 118, 137, and 160° are reported. Comparisons are made using several scaling variables.
