用全核加关联方法计算了类锂体系从Z=3到20的基态的四极和八极极化率。对于中性锂原子，分析了四极和八极极化率的典型收敛模式。计算了锂原子基态的四极和八极极化率，并与以前用其他方法得到的理论结果进行了比较，我们的预测与文献中最准确的报道相吻合。对于类锂离子，我们的预测可能会为今后其他精确的理论计算提供有价值的参考数据。
The quadrupole and octupole polarizabilities for the ground states of lithiumlike systems from Z=3 to 20 are calculated with the full-core plus correlation method. For the neutral lithium atom, the typical patterns of convergence of the quadrupole and octupole polarizabilities are analyzed. The calculated quadrupole and octupole polarizabilities of the ground state for lithium atom are compared with the previous theoretical results obtained by other methods; our predictions agree with the most accurate reports in the literature very well. For lithiumlike ions, our prediction may provide valuable reference data for other accurate theoretical calculations in future.
