【 摘 要 】

The rotational bands of α +15O(1/2-) in19Ne are calculated by employing a simple potential model. The α-15O interaction potential is constructed from the scattering calculation of its mirror system, α +15N. The resonance states are identified by imposing the absorbing boundary condition. The present calculations predict the sequence of the spin-orbit splitting states in the unbound region of19Ne, which are generated from the higher spin states in the20Ne nucleus. The excitation function of the α +15O elastic scattering is also predicted, and the appropriate condition to observe the resonances is also discussed.
