Wavelengths and transition probabilities in heavy Ge-like ions (70 ⩽ Z ⩽ 92)

Wavelengths and transition probabilities have been calculated for the 4s24p2–4s4p3 and 4s24p2–4s24p4d allowed transitions and for the forbidden (M1 and E2) transitions occurring within the ground configuration (4s24p2) in the heavy Ge-like ions with Z = 70–92. The fully relativistic multiconfiguration Dirac–Fock method taking into account both the correlations within the n = 4 complex and the QED effects has been used for the calculations. The present results are compared to and agree well with recent electron-beam ion-trap measurements in tungsten, osmium, gold, bismuth, thorium, and uranium.
