Why Are Most Nuclei Axially Symmetric?

Warum sind die meisten Kerne axialsymmetrisch?

A previous publication was concerned with the average prolateness of nuclei [1]. With the same methods as there it is shown here that axial symmetry should be predominant in nuclei, which it is indeed. The tools for the proof are special collective and single particle coordinates. The nucleon-nucleus interaction is approximated by a shell model potential plus Nilsson coupling; strong coupling is used. The minimum of the total energy is found for axial symmetry.
