Abstract

The

{}^{11}B

and

{}^{11}C

T = \frac{3}{2}

analogs of the

{}^{11}{Be}

(0.32-MeV) state have been located utilizing the

{}^{13}C (p, {}^{3}{He}) {}^{11}B

and

{}^{13}C (p, t) {}^{11}C

reactions. The new states lie at 12.94±0.05 MeV in

{}^{11}B

and at 12.47±0.06 MeV in

{}^{11}C

, and have total widths of 350±50 and 550±50 keV, respectively; their spins and parities are found to be

½^{-}

. A check on their isospin purity is achieved by examination of their charged-particle decay properties; it is found that the major decay mode is via

L = 1

isospin-allowed proton emission.
