Cluster structures in 19Ne are studied by the microscopic and macroscopic cluster models. In the microscopic calculation, the coupled-channels problem of (α+15O) + (3He+16O) are solved, and the calculated energy spectra nicely reproduce the low-lying levels. In the macroscopic approach, the α + 15O potential model is applied. The calculation of the potential model predicts the existence of the resonances above the α threshold, which has a weak-coupling structure of the α particle plus one hole inside of the 16O nucleus. The coupling effect of the 5p–2h configuration to 19Ne is briefly discussed.
