摘要

Nuclei consist of up to hundreds of nucleons orbiting the nucleus billions of times per second, filling 60 % of the nuclear volume, and interacting with both the strong and electromagnetic forces. One might expect complete chaos but nuclei exhibit astonishing simplicities and regularities. These can be understood with simple concepts of structure, the effects of the Pauli Principle, and the appearance of various symmetries. New horizons in nuclear structure, enabled by new technology, are radically changing our ideas about the nucleus and the models that describe it.
