The neutron-rich isotopes are investigated by large-scale shell-model calculations with the extended pairing plus multipole-multipole force (EPQQM model). The orbits of are included for both proton and neutron model space, while two more neutron orbits above the shell gap are included to study neutron-core excitations. The higher core-excited states in are calculated for the first time in this region. The present work well describes both the low-lying and the high-energy states for , , and , as well as the low-lying levels of and . The several multiplets with clear boundary exist in , while a new configuration lying between 4.8 and 6.0 MeV is found as a theoretical prediction in . Finally, the transition probabilities in these nuclei are calculated and compared with available data. The predicted energy levels and electromagnetic transition will be useful for planning future experiments.
