RELATION BETWEEN TWO KINDS OF MOMENT OF INERTIA AND NUCLEAR TRIAXIALITY

The important fact that the second kind of moment of inertia J⁽²⁾ is larger than the first kind of moment of inertia J⁽¹⁾ can be derived naturally from the 2-parameter expression for the rotational spectra, E(I)=a(√1+bI(I+1)-1), in its derivation the nuclear triaxiality has been taken into account.
