We propose to return to the old quantum theory of Bohr-Sommerfeld to search for a new Ersatz Model of the atom where the four quantum numbers are related to electron orbitals.
There are two more topological quantum numbers which relate to spin and photon number.
The two particle states are defined by four quantum numbers j = (n,m;N,M) and [alpha] = (r,s;R,S), where n, N, r, R are the main quantum numbers and m, M, s, S are the angular momenta of entering single particle states.
In our numerical work, we solve (6) with the adiabatic potential (7) by using the numerical trigonometric sweep method [23] and we find electron energies [E.sub.m,n] for twenty different magnetic quantum numbers m = 0,-1, -2, ..., -19 and two different axial quantum numbers n= 1,2.
Using different approximations, considerable efforts have been made for calculating these integrals over STOs with noninteger principal quantum numbers n (NISTOs).
Their topics include quantum chromodynamics and deep inelastic scattering, the number of neutrinos and the Z line shape, asymmetries at the Z poles: the quark and lepton quantum numbers, theoretical aspects of the production of electroweak bosons at hadron colliders, rare decays probing physics beyond the standard theory, and the supersymmetry standard model.
For the first time settlement and experimentally investigated for a round galvanized steel wires, is confirmed the important fundamentals of the theory of electricity electrophysical the fact that in this metal conductor used with aperiodic pulsed axial current conduction time form 9 ms/160 ms and high density (about 0.37 kA/[mm.sup.2]) in the longitudinal direction extend quantized coherent electronic half-wave of de Broglie length [[lambda].sub.enz]/2 defined during the investigations by the quantum numbers n=1,3,9.
Figure 2(b) demonstrates how the potential peaks (corresponding to the local maximum for the [V.sub.eff]) depend on the radius of the buckyball for various angular momentum quantum numbers L.
