Energies, wavelengths, transition probabilities, and oscillator strengthshave been calculated for the 4s24p2-4s4p3, 4s24p2-4s24p4d and 4s4p3-4p4 allowedtransitions in heavy Ge-like ions with Z=59-63. The fully relativisticMulticonfiguration Dirac-Fock (MCDF) method taking into account both thecorrelations within the n=4 complex and the quantum electrodynamic (QED)effects have been used in the calculations. MCDFGME code is used to calculateelectron impact excitation cross sections for the 4s24p2-4s4p3 and4s24p2-4s24p4d transitions with plane-wave Born approximation. The results ofPr XXVIII, Nd XXIX, Pm XXX, Sm XXXI and Eu XXXII are compared with HFR methodresults.
