The tin isotope 100Sn is of singular interest for nuclear structure due to its closed-shell proton and neutron configurations. It is also the heaviest nucleus comprising protons and neutrons in equal numbers—a feature that enhances the contribution of the short-range proton–neutron pairing interaction and strongly influences its decay via the weak interaction. Decay studies in the region of 100Sn have attempted to prove its doubly magic character1 but few have studied it from an ab initio… Expand

Close to the edge
The tin isotope 100Sn is key to understanding nuclear stability, but little is known about its properties. Precision measurements of closely related indium isotopes have now pinned down its mass.

β decays of the heaviest N = Z − 1 nuclei and proton instability of 97 In †
Interesting nuclear structure phenomena can be observed at the limits of neutron or proton binding, providing sensitive probes of shell evolution and/or collective behaviors. Studies have found theExpand
Masses of exotic calcium isotopes pin down nuclear forces
TLDR
The mass determination of the exotic calcium isotopes 53Ca and 54Ca is reported, using the multi-reflection time-of-flight mass spectrometer of ISOLTRAP at CERN, to establish a prominent shell closure at neutron number N = 32, in excellent agreement with the theoretical calculations. Expand
Superallowed Gamow–Teller decay of the doubly magic nucleus 100Sn
TLDR
Measurements of the half-life and decay energy for the decay of 100Sn, the heaviest doubly magic nucleus with equal numbers of protons and neutrons, establish the ‘superallowed’ nature of this Gamow–Teller transition. Expand
Unexpectedly large charge radii of neutron-rich calcium isotopes
Despite being a complex many-body system, the atomic nucleus exhibits simple structures for certain ‘magic’ numbers of protons and neutrons. The calcium chain in particular is both unique andExpand
Measurement and microscopic description of odd–even staggering of charge radii of exotic copper isotopes
Nuclear charge radii globally scale with atomic mass number A as A 1∕3 , and isotopes with an odd number of neutrons are usually slightly smaller in size than their even-neutron neighbours. ThisExpand
The magic nature of 132Sn explored through the single-particle states of 133Sn
TLDR
Here, the single-particle character of the levels in 133Sn that lie outside the double shell closure present at the short-lived nucleus 132Sn are measured using an inverse kinematics technique that involves the transfer of a single nucleon to the nucleus. Expand
Beta decay of 103Sn
Abstract.The β decay of 103Sn, a three-neutron-particle nucleus with respect to the 100Sn core, was investigated at the GSI on-line mass separator using an array of 17 germanium crystals and a totalExpand

First Glimpse of the N=82 Shell Closure below Z=50 from Masses of Neutron-Rich Cadmium Isotopes and Isomers.
TLDR
The N=82 nuclear shell closure is probed by mass measurements of neutron-rich cadmium isotopes with the ISOLTRAP spectrometer at ISOLDE-CERN by using the recently implemented phase-imaging ion-cyclotron-resonance method and the ordering of the low-lying isomers in ^{129}Cd and their energies are determined.
