Description
One of the goals of nuclear physics is to understand the properties of
all of the atomic nuclei including ones with large proton-neutron
asymmetry. The nuclear shell structure is a key to understanding the
strongly-interacting many-nucleon system and the doubly magic nucleus is
a cornerstone for that. The shell structure and magic numbers are well
established from the studies of stable nuclei, while the magic numbers
can change when the proton and neutron numbers are much different from
the stable nuclei. Among the stable and unstable nuclei, the candidates
of doubly magic nuclei are very limited. The neutron-rich oxygen isotope
28O was the only one that is experimentally accessible that had yet to
be observed. In the presentation, I will mainly focus on recent
experimental study on 28O and its neighbor 27O.
