Abstract
Oscillator strengths for the electric dipole transitions within the ground complex of the boron isoelectronic sequence have been calculated up to Np88+ from the relativistic parametric potential method. The electrostatic interaction between the states of the complex is explicitly introduced. The Z dependence of the f values for low and high stages of ionisation can be understood within the frame of the relativistic Z expansion method. For intermediate Z values, anticrossings appear between levels belonging to the same configuration; these anticrossings can give rise to striking irregularities in the trends of the f values. Finally the behaviour of the oscillator strengths throughout the sequence can be explained.Keywords
