Résumé : The C10+α elastic cross section was measured to investigate the structure of the proton-rich O14 nucleus. A radioactive beam of C10 was produced at the RI beam separator CRIB using the B10(p,n)C10 reaction with a B10 beam energy of 6.99 MeV/nucleon. A complex resonant structure is observed in O14 in the excitation energy region around 13-18 MeV, improving significantly our knowledge on the structure of this nucleus. An R-matrix analysis was performed to determine the properties of resonances. α clustering structure is observed for J=0+ and J=2+ at 13.44 and 14.88 MeV, respectively. These results are compared with the α clustering structure reported in the mirror nucleus C14.
