Abstract The mass of 13 Be has been measured with the reaction 13 C(14 C,14 O)13 Be at E Lab =337 MeV. A Q-value of Q 0=−37.02(5) MeV was obtained and the mass excess is M.E.=35.16(5) MeV. If the observed line corresponds to the ground state,13 Be is particle unstable with respect to the oneneutron emission by 2.01 MeV. The observed line width of 0.3(2) MeV supports an assignment ofJ π=5/2+ or 1/2−, but excludesJ π=1/2+. An excited state is seen at 3.12(7) MeV; there are indications of a second excited state at 6.5(2) MeV.
