✦ Synopsis


The order of increasing antibonding energy of the 4f orbitals is calculated in nine crystals from the operator of kinetic energy with a reliability around 0.9 (excepting Nd,O,S).

The energy differences seem scaled with factors close to 1.2, and the ratio between the antibonding effect and the square of the overlap integral is shown to be somewhat higher than 100 eV. Little necessity seems to remain for adding the non-spherical part of the Madelung potential.
