0g.s.+用重离子非弹性散射逆运动学方法研究了丰中子核~（28）Ne的→ ~（21+）激发。B（E2;0g.s.+→21+）值被确定为132（23）e2 fm 4，其小于根据第一21+态的低激发能量所预期的值。与理论预测的比较表明，抑制集体in 28 Ne的特征在于核的边界上的“反转岛”。
The 0g.s.+→21+excitation of the neutron-rich nucleus28Ne has been investigated via heavy-ion inelastic scattering in reversed kinematics. The B(E2;0g.s.+→21+) value was determined to be 132(23)e2fm4, which is smaller than expected from the low excitation energy of the first 21+state. A comparison with theoretical predictions suggests that the suppressed collectivity in28Ne is characteristic of nuclei lying on the boundary of the ‘island of inversion’.
