Abstract

Single-particle properties of low-lying resonance levels in ¹⁴O have been studied efficiently by utilizing a technique of proton elastic resonance scattering with a ¹³N secondary beam and a thick proton target. The excitation functions for the ¹³N + p elastic scattering were measured over a wide energy range of E_CM = 0.4 - 3.3 MeV and fitted with an R-matrix calculation. A clear assignment of J^π = 2^- has been made for the level at E_x = 6.767 (11) MeV in ¹⁴O for the first time. The excitation functions show a signature of a new 0^- level at E_x = 5.71 (2) MeV with Γ = 400 (100) keV. The excitation energies and widths of the ¹⁴O levels are discussed in conjunction with the spectroscopic structure of A = 14 nuclei with T = 1.
