- 論文の詳細を見る
A real-particle RPA formalism for open-shell nuclei is presented which can be applied to both isoscalar vibration and isospin-splitting isovector vibration. In order to keep boson approximation meaningful even under the existence of partially-occupied orbits, one-body operator for description of normal mode is modified by means of projection operators which project onto wave functions with stretched seniority, defined in the isospin formalism, and with specific reduced isospin. Validity of boson approximation ensures hermiticity of RPA equations of motion and clarifies association with quasi-particle RPA. Nuclear excitation arising from the rearrangement of nucleons in the same partially-occupied orbit can be taken into account, while it is impossible in the RPA by Rowe who adopted one-body operators themselves for description of normal mode.
