Résumé : | The structure of 18Ne, and in particular of the 1- (6.18 MeV) level, is investigated in a microscopic cluster model involving 16O+p+p configurations. We use the three-cluster generator coordinate method associated with the hyperspherical formalism. The spectroscopy of 18Ne and 18O low-lying states is analyzed. Using the analytical continuation in the coupling constant (ACCC) method, we determine the width of the 1- (6.15 MeV) resonance in 18Ne and find Γ = 40 10 keV. This result is in fair agreement with experiment (50 5 keV). © 2010 IOP Publishing Ltd. |
