At this moment we can be satisfied to say that the stability theorem leads to the known solution: there are only labile neutral elementary particles. Now let us check whether this model of an uncharged elementary particle also provides information about the other characteristics of the uncharged particle that is consistent with experience. This will best be achieved if we individually examine our models of Table 2 by focusing on the theorem elaborated above. Let us start with the µ-meson (model TaOu). If here two charges with opposite sign travel diametrically along the proposed model’s orbit and in the same orientation, their joint movement will come to a sudden stop because both simultaneously complete a spin rosette, these two spin rosettes being absolutely congruent. However, the magnetic fields of external interaction prevent the free movement of the particles to be continued. The stability theorem is not fulfilled and we may say – in total harmony with the natural conditions – that there can’t be an uncharged μ-meson.

Now we come to the π-meson model (model Tu). We look along the spin axis and get the two charges started – as agreed – diametrically in the same sense of revolution. But now it becomes difficult: due to the specific character of the orbit rule outlined above there are only two constellations of the two electrons in which the electrons are actually diametrically arranged. At all other orbital points the common secant closely bypasses the center of the sphere! Thus, the stability theorem is not fulfilled in this direction. However, the deviation of the secant from the center of the sphere is oscillating, in that the particle that initially lags behind the counterpoint of the other one will lead in the next half revolution, so that one could speak about a (certainly labile) minimal change of external electrostatic interaction. In respect of the external magnetic interaction there is no reason for such a “catastrophe” as with the μ-meson, since both charges terminate one revolution at different locations so that a synergy of the “spin magnets” is unimaginable. (Here we may speak about electrostatic and magnetic interactions because we discuss external interaction in which pure electric und pure magnetic energies exist.) Now we will take a look at Fig. 27 and ask if the magnetic fields of the self-interaction could influence each other. This question may be denied because every particle interacts with itself at every point of the orbit in another spatial direction than its partner.
