Abstract：
Static and dynamic quadrupole (Q) moments of C and Ne isotopes are investigated by using Skyrme Hartree-Fock and shell model wave functions. We point out that the deformation of C isotopes have a strong isotope dependence as a manifestation of nuclear Jahn-Teller effect. It is shown at the same time that the Q moments and the magnetic moments of the odd C isotopes depend clearly on assigned configurations, and their experimental data will be useful to determine the spin-parities and the deformations of the ground states of these nuclei. Electric quadrupole (E2) transitions in even C and Ne isotopes are also studied by using the polarization charges obtained by the particle-vibration coupling model for shell model wave functions.
