We would like to thank Dr. S. Watanabe, Mr. Y. Ohshiro, Mr. N. Yamazaki, and Dr. Y. Mizoi for their contribution to the construction of CRIB. We also thank the CNS/RIKEN staff members for their operation of the ion source and the cyclotron. We are grateful to Prof. T. Motobayashi and Mr. T. Minemura for their experimental information. The present study was partially supported by Grant-in-Aid for Science Research from the Japan Ministry of Education, Culture, Sports, and Technology under the contract numbers 13440071 and 14740156, and also by the Joint Research Program under the Korea–Japan Basic Science Promotion Program (KOSEF 2002-JR015).

N2 - Resonance states in 12N were studied by using the resonance elastic scattering of 11C + p with a low-energy radioactive ion beam of 11C at 3.5 MeV/nucleon and a thick (CH2)n target. The 11C beam was separated by a newly installed CNS radioactive ion beam separator (CRIB). The energy spectrum of recoil protons was measured at laboratory scattering angles around θLAB = 0° to identify resonance states in 12N. The spin-parity values of Jπ = 3- and (2)+ have been determined for the levels at the excitation energies of Ex = 3.1 and 3.6 MeV in 12N, respectively, suggesting a small contribution of the 3.1-MeV level to the 11C(p,γ)12N stellar reaction.
