Abstract:

 The extended optimal level version of the multiconfiguration Dirac-Fock (MCDF) and relativistic configuration interaction (RCI) calculations strength with the inclusion of Breit interaction, vacuum polarization, self energy and finite nuclear mass corrections in the active interaction approach has been used to calculate the fine-structure intervals, transition rates and oscillator strengths for the magnetic dipole of the interval transitions among 1s²2s2p ³P_{0, 1}Keylevels of ions in the beryllium isoelectronic sequence with a nuclear charge Z ranging from 6 to 80. A comprehensive comparison of present results is performed with other recent available values.

Key words: Be-like ion; multiconfiguration Dirac-Fock (MCDF); transition rates; oscillator strengths
