Cross sections for proton-induced spallation of ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ leading to nuclides with mass 6 or mass 7 were measured at proton energies between 30 and 40 MeV. Time-of-flight techniques were used for mass identification.

NUCLEAR REACTIONS ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}+p$ $E=30.0, 35.0, 40.0$ MeV; measured spallation $\sigma$ for producing masses 6, 7; gas targets. Discuss astrophysical significance.
