  The structure of the neutron-deficient 9C isotope was studied via elastic
scattering of radioactive 8B on protons. An excitation function for resonance
elastic scattering was measured in the energy range from 0.5 to 3.2 MeV in the
center-of-momentum system. A new excited state in 9C was observed at an
excitation energy of 3.6 MeV. An R-matrix analysis indicates spin-parity 5/2-
for the new state. The results of this experiment are compared with Continuum
Shell Model calculations.
