It was F003200100013 subsequently determined by measuring the width of the F003200100014 observed photopeaks of gamma-rays from the nonresonant F003200100015 Li-6(p,gamma0)Be-7 reaction that the alloy layer was F003200100016 50 keV thick to 600 keV protons. F003200100017 (2) Thinner target was prepared by direct evaporation F003200100018 of lithium oxide isotopically enriched to 99% 6Li onto F003200100019 a 0.025 cm thick fine gold substrate. F003200100020 The Li content of this target was determined using the F003200100021 narrow resonance in the Li-6(alpha,gamma)Li-10 reactionF003200100022 at an alpha-particle bombarding energy of 1175 keV as F003200100023 in paper of F.Ajzenberg-Selove (see REL-REF).
