Relativistic effects in E1 transition oscillator strengths along the Yb+ isoelectronic sequence

Electric dipole transition oscillator strengths have been computed for low-lying transitions in the Yb+ isoelectronic sequence ( through Ra19+) in fully relativistic and non-relativistic-limit approximations. Relativistic effects were carefully investigated and efforts were undertaken to establish systematic trends in relativistic contributions to oscillator strengths along the Yb+ isoelectronic sequence.
