The properties of resonances in the ¹⁸O+α interaction are important for analyses of astrophysical processes and for understanding of the development of the α-cluster structure with addition of neutrons to 4N nuclei. Previous high-energy resolution measurements have not been treated using the contemporary R-matrix approach. We have performed an R-matrix analysis of the resonant data [D. Powers, J. K. Bair, J. L. C. Ford, Jr., and H. B. Willard, Phys. Rev. 134, B1237 (1964)] and obtained new data on 15 levels in the excitation region of 11.7--12.5 MeV ²²Ne. It appears that the model calculations did not predict the observed tendency in the ²⁰⁻⁻²²Ne α clustering. This paper is the first step of our program of investigation of the ²²Ne spectrum in resonant reactions.
