Recent advances in shell evolution with shell-model calculations

Shell evolution in exotic nuclei is investigated with large-scale shell-model calculations. After presenting that the central and tensor forces produce distinctive ways of shell evolution, we show several recent results: (1) evolution of single-particle-like levels in antimony and cupper isotopes, (2) shape coexistence in nickel isotopes understood in terms of configuration-dependent shell structure, and (3) prediction of the evolution of the recently established N = 34 magic number towards smaller proton numbers. In any case, large-scale shell-model calculations play indispensable roles in describing the interplay between single-particle character and correlation. (author)
