Abstract

The mass of ${}^{11}{Li}$ has been determined from $Q$ -value measurements of the ${}^{1}H ({}^{11}{Li}, {}^{9}{Li}) {}^{3}H$ reaction. The experiment was performed at TRIUMF laboratory with the GANIL active target MAYA. Energy-energy and angle-angle kinematics reconstruction give a $Q$ value of 8.119(22) MeV for the reaction. The derived ${}^{11}{Li}$ two-neutron separation energy is $S_{2 n} = 363 (22)$ keV.
