The lifetime of the 1s22s3p 3P0 level of selected Be-like ions, from Z = 5 to Z = 92, is calculated using the multiconfiguration Dirac-Fock method including QED corrections. Full correlation up to the 4f subshell in both initial and final levels for all possible decay modes was included. The results are in reasonable agreement with the scarce existing experimental and theoretical data.
