摘要：

A possible role of the electron interaction in the morphology of the microcluster is studied. Highly symmetrical configuration leads to highly degenerated single-particlelevels. They are preferable for the emergence of the magnetic polarization (the Hundtendency). On the other hand, the splitting of the degenerated Fermi level due to the lowering of the symmetry sometimes reduces the ground state energy (the Jahn-Teller tendency). The conflict of these two tendencies is investigated by a simple model. © 1979 Springer-Verlag.
