Abstract

The ground-state mass of

{}^{12}{Be}

was measured using the reaction

{}^{7}{Li}

(

{}^{7}{Li}

, 2p)

{}^{12}{Be}

in a kinematically complete experiment. The mass excess was determined to be 24.95 ± 0.10 MeV. An excited state of

{}^{12}{Be}

is identified at an excitation energy of 0.81 ± 0.10 MeV.
