Atomic nuclei have a shell structure that allows for 'magic numbers' of neutrons and protons, analogous to the noble gases in atomic physics. Knowledge of the properties of single-particle states outside nuclear shell closures in exotic nuclei is important for the fundamental understanding of nuclear structure and nucleosynthesis. Here, a nucleon-transfer technique has been used to measure the single-particle states of 133Sn, revealing the highly magic nature of 132Sn.
