A 42 MeV $^{14}$C beam was used to populate states of excitation energy up to 14.9 MeV in $^{18}$O. The analysis was performed using a multi-level, multi-channel R-Matrix approach.\n  Resu","authors_text":"A. S. Volya, E. D. Johnson, G. V. Rogachev, K. W. Kemper, M. L. Avila, V. Z. Goldberg, Yu. M.
