Total energies of several configurations of the elements in the range of atomic numbers 104–132 were computed using the Liberman–Waber–Cromer program to determine the probable ground-state configurations. These calculations provide evidence for eka-actinium (s2d) at 121, partial filling of the 6f shell through 124 and beginning of a new superactinide series at element 125, in which the 5g shells fill progressively as the atomic number increases.
