Abstract

The mass of the nucleus ${}^{11}{Li}$ has been determined from a measurement of the $Q$ value of the reaction ${}^{14}C$ ( ${}^{11}B$ , ${}^{11}{Li}$ ) ${}^{14}O$ at $\frac{E}{A} \approx 32$ MeV. The results, which indicate a two-neutron separation energy of $S_{2 n} ({}^{11}{Li}) = 295 \pm 35$ keV, put this basic quantity on a firm basis for use in theoretical models of the halo nucleus ${}^{11}{Li}$ .
