Alpha resonant states in 13C up to 15 MeV were excited by the 9Be (6Li,d) 13C reaction. The data were taken at a bombarding energy of 25.5 MeV employing the S˜ao Paulo- Pelletron-Enge Split Pole facility and the nuclear emulsion technique. The resolution of 50 keV allowed for the separation of the resonant contributions to the known 7/2− and (5/2−) states near the 9Be + threshold both associated with an L = 4 transfer. Several narrow alpha resonant states not previously measured were detected, in particular the one at the 3 + n threshold populated by an L = 2 transfer, revealing a 9Be + component for the 1/2− cluster state candidate at this threshold.
