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.
