Let us emphasize at this point that the tetrahedral configurations, as predicted by theory, are markedly non-axial and, therefore, are expected to strongly mix components of wave-functions with various quantum numbers : the strongest component associated with the geometry of shapes based on the spherical harmonics should be . Theoretical calculations based on the generalised collective rotor Hamiltonian that includes terms of the third order in angular momentum2 indicate that the structure of the wave-function of the state is exceptional since, in contrast to states with , it must not manifest the tetrahedral symmetry. In other words, for the tetrahedral symmetry is excluded; actually state wave-function manifest an axial symmetry. Consequently, the role of the state, often treated as a member of the (expected to be) the tetrahedral band, is special in that even if connected to the state via an E2 transition, in principle possible due to an expected to be strong a K-mixing, its underlying symmetry must not be tetrahedral. Our experiement, similarly to the preceding ones, gives no sign of the transition either what signifies that the corresponding E2 transition, if exists, must be very weak.
