Spectroscopy of 9C via resonance scattering of protons on 8B

Abstract

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.
