英文摘要: With the relativistic Coulomb wave function boundary condition, the energies, widths and wave functions of the single-proton resonant orbitals for Ne-17 are studied by the analytical continuation in the coupling constant (ACCC) approach within the framework of the relativistic mean field (RMF) theory. Pairing correlations and contributions from the single-particle resonant orbitals in the continuum are taken into consideration by the resonant Bardeen-Cooper-Schrieffer (BCS) approach, in which the constant pairing strength is used. It can be seen that the fully self-consistent calculations with NL3 and NLSH effective interactions mostly agree with the latest experimental measurements, such as binding energies, matter radii, charge radii and densities. The energy of the pi 2s(1/2) orbital is slightly higher than that of the pi 1d(5/2) orbital, and the occupation probability of the (pi 2s(1/2))(2) orbital is about 20%, which is in accordance with the shell model calculation and three-body model estimation.
