TL;DR: Low-lying excited states of ^{40}Mg have been studied for the first time following a one-proton removal reaction from ^{41}Al, suggesting an excitation spectrum that shows unexpected properties as compared to both the systematics along the Z=12, N≥20 Mg isotopes and available state-of-the-art theoretical model predictions.

TL;DR: In this article, the authors reported the measurement of reaction cross sections (σR}^{ex}) of 27,29,F with a carbon target at RIKEN and attributed the halo to neutrons occupying the 2p 3/2 orbital, thereby vanishing the shell closure associated with the neutron number N=20.

TL;DR: In this article, the formation of α clusters at the surface of neutron-rich tin isotopes has been investigated using quasi-free α cluster-knockout reactions, and the observed monotonous decrease of reaction cross sections with increasing mass number implies a tight interplay between α-cluster formation and the neutron skin.

TL;DR: In this article, a detailed spectroscopy of the neutron-unbound nucleus was performed for the first time following proton/neutron removal from the nucleus, and the invariant-mass spectra were reconstructed for both the ground state and ground state.
