| Research Abstract |
Low-lying states for even-even, odd-mass, and doubly odd nuclei around the mass 130 are systematically investigated using a pair-truncated shell model. Energy levels of the low-lying collective states for even-even Xe, Ba, Ce, and Nd isotopes are reproduced very well along with electromagnetic transitions. For odd-mass and doubly odd nuclei, complicated level schemes and electromagnetic moments are in excellent agreement with the experimental data. Using wave functions obtained in these calculations, the Schiff moments for the lowest 1/2^+states of Xe isotopes are calculated. The upper limit for the electric dipole moment of a ^<129>Xe neutral atom is estimated using its nuclear Schiff moment.
