Abstract

The complex scaling method is extended to the relativistic framework for describing deformed nuclei and the theoretical formalism is presented in detail. How to expose the resonant states is demonstrated, and the applicability and efficiency of the extended method are confirmed. The energies and widths of the single-particle resonant states in nuclei with A=31 are determined, and the structure of single-particle levels for bound and resonant states is shown to be similar to that in the nonrelativistic calculations. Especially, the present formalism has yielded richer numerical results for the resonant levels than those obtained by the coupled-channel method in relativistic and nonrelativistic calculations.
