Summary:The ＂island of inversion＂ has been known for over a quar- ter century, since Warburton et al. [1] proposed that nuclei with intruder ground states would constitute a 3x3 square with Z=10-12, N=20-22 in 1990. Uncovering the underlying inversion mechanism and exploring the scope of the island have attracted significant theoretical and experimental efforts in the following years. Now it is well known that the reduction of N=20 shell gap, which is likely caused by the strong nucleon-nucleon tensor interaction [2-5], allows the intrusion of neutron orbits from the pf shell into the sd shell and results in the inversion of the 2p-2h intruder and 0p-0h normal con- figurations of the nuclear ground states in this region. Mean- while, the original border of the ＂island of inversion＂ has been extended greatly [6-14].
