In this paper, we used the multiconfiguration Dirac-Fock method to compute with high precision the 1[ital s][sup 2]2[ital s]2[ital p] [sup 3][ital P][sub 1]--1[ital s][sup 2]2[ital s]2[ital p] [sup 3][ital P][sub 0] separation energy in berylliumlike ions, including the relativistic contribution to electron-electron correlations and radiative corrections. The effect of the hyperfine interaction on both the energy and lifetimes of those levels has been evaluated. In the absence of nuclear magnetic moment the [sup 3][ital P][sub 0] level can decay to the ground state only by an [ital E]1-[ital M]1 transition, with a very low probability. We show that the hyperfine interaction increases dramatically the [sup 3][ital P][sub 0] transition probability.
