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}

.
