- Abstract
- Single-particle properties of low-lying resonance levels in O-14 have been studied efficiently by utilizing a technique of proton elastic resonance scattering with a N-13 secondary beam and a thick proton target. The excitation functions for the N-13 + 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(pi) = 2(-) has been made for the level at E-x = 6.767 (11) MeV in O-14 for the first time. The excitation functions show a signature of a new 0(-) level at E-x = 5.71(2) MeV with F = 400(100) keV. The excitation energies and widths of the O-14 levels are discussed in conjunction with the spectroscopic structure of A = 14 nuclei with T = 1. (C) 2007 Elsevier B.V. All rights reserved.
