Yoneda (米田健一郎) With new-generation facilities able to provide beams of very unstable nuclei, one can explore how the traditional magic numbers and shell closures become fragile and break down in neutron-rich regions of the chart of nuclides. One important such region is near 32 Mg, the so-called ”island of inversion”, suggesting a rearrangement of the nuclear shell structure. This study reports on B ( E 2 ) transition probabilities for the most neutron-rich nuclei yet measured in that region, 30 Ne and 36 Mg. The results help map the evolution and extent of anomalous shell structure toward the neutron drip line. [Phys. Rev. C 93, 044306] Published Mon Apr 11, 2016
