Abstract

The K-mixing effect is investigated for triaxial deformation through the angular momentum projection technique. The mathematical nature of the norm overlap kernels is discussed in terms of the Fourier analysis. A relation between the signature symmetry and the K quantum number is discussed. A non-cranked Hartree-Fock state is shown to be a K=0 dominating state. The spread of the K distribution happens in a symmetrical manner and the K-mixing is enhanced as triaxial deformation is enlarged. On the contrary, the J=0 component is contained only slightly against a naive expectation.
