Using the deformed Skyrme Hartree-Fock approximation together with pairing correlation, we studied the static and dynamic quadrupole moments of C and Ne isotopes and the evolution of quadrupole deformatious in sd-and pf-shell nuclei with mass A =18-56.It is found that the defor mations of C and Ne isotopes have a strong isotope dependence as a manifestation of spontaneous symmetry breaking effect in nuclear physics.It is shown at the same time that the quadrupole moments Q and the magnetic moments m of the odd C and odd Ne isotopes depend clearly on assigned configurations.
