The inclusive energy spectra of ${}_{}{}^{6,7}{}_{}{}^{}\mathrm{Li}$ ejectiles from the reaction ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$ + Au at 27.4 MeV/nucleon have been measured. The quasielastic peaks for ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ and ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ have reduced momentum widths ${\sigma }_0$ of 65 and 60 MeV/c, respectively. When plotted in conjunction with similar measurements, these new results clarify the behavior of the reduced momentum width in the important region between 10-100 MeV/nucleon.

NUCLEAR REACTIONS ${}_{}{}^9{}_{}{}^{}\mathrm{Be}+\mathrm{Au}\to {}_{}{}^{6,7}{}_{}{}^{}\mathrm{Li}+X$. $E\left({}_{}{}^9{}_{}{}^{}\mathrm{Be}\right)=27\mathrm{}$ MeV/nucleon. Measured momentum widths of ${}_{}{}^{6,7}{}_{}{}^{}\mathrm{Li}$ ejectiles. Deduced reduced width ${\sigma }_0$. Discuss ${\sigma }_0$ over energy range 10-2000 MeV/nucleon.
