As part of the well-known task about a motion of charged particle in central forces field, a certain parallelism for electronic distribution between the atomic and subatomic ''orbits'' can be established.
In this conjuncture the ground state of muonium atom as in transition electron-nuclear structure is highlighted.
Moreover, there is specifically nuclear solution of fine-structure constant which with a hyper-fine structure, like of the Lamb shift of hydrogen atom, is unambiguously associated.
Such a special approach, in the terms of electric interaction, may serve as an extension to the existing meson-boson classification.
In particular, some idea about a versatility of the Higgs mechanism in nuclear reactions put forward for consideration here.
But it would be just spatial abstraction, where subatomic matter expands as into infinity.
And what would be beyond the edge of the universe?
