Orbital Collapse of the 5g-Electrons in the Superheavy Elements of the 8th Period

The presence of the orbital collapse of the g -orbitals in the excited state of the atom with the nuclear charge number Z = 124 and in the ground state of the atom with Z = 125, which belong to the 8th period of the extended periodic table, is demonstrated. In both cases, the orbital collapse occurs...

Description
Summary:The presence of the orbital collapse of the g -orbitals in the excited state of the atom with the nuclear charge number Z = 124 and in the ground state of the atom with Z = 125, which belong to the 8th period of the extended periodic table, is demonstrated. In both cases, the orbital collapse occurs within the same configuration when increasing the total angular momentum J , which characterizes the relativistic term of the atom in the jj coupling. All calculations are performed by means of the relativistic Dirac–Fock method.
