摘　　要：In this paper, we explored the characteristics of the interference effects between perturbative states in hyperfine induced 2s2p ^3p0,^3p2→ 2s^21S0 transitions of Be-like ions. It was found that the interference effects non-monotonically change with increasing atomic number Z in these two transitions. The strongest interference effect is near Z = 9 for 2s2p^3P0→2s^21S0 transition and near Z = 7 for the other.In this paper, we explored the characteristics of the interference effects between perturbative states in hyperfine induced 2s2p ^3p0,^3p2→ 2s^21S0 transitions of Be-like ions.
