Abstract：
Variational method and TDA approximation was applied to construct the SD pairs in the SD-pair shell model (SDPSM). The results show that this new method seems better than the surface δ-interaction in determining the pair structure of the SDPSM in the description of collectivity of low-lying spectra of nuclei.
