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.
