Cross sections for the ${}_{}{}^6{}_{}{}^{}\mathrm{Li}({}_{}{}^3{}_{}{}^{}\mathrm{He}, p)$ reaction at energies below 2 MeV

Absolute cross sections for the ${}_{}{}^6{}_{}{}^{}\mathrm{Li}({}_{}{}^3{}_{}{}^{}\mathrm{He}, p)$ reaction to the ground, 2.94-, 16.63-, and 16.92-MeV states in ${}_{}{}^8{}_{}{}^{}\mathrm{Be}$, as well as for the total underlying proton continuum, have been obtained for incident ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ energies between ∼0.5 and 1.85 MeV. Differential and total (integrated) reaction cross sections with accuracies of 10-20% are presented. Thermonuclear reaction-rate parameters are calculated. Interpretation of the observed proton and alpha particle continuous spectra is discussed.
