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, the authors investigated the cross-shell effects in the region of the N = 20 island of inversion at Z = 12 and concluded that crossshell effects play a major role in the structure of 30Mg.

TL;DR: Lifetime measurements of excited states in the neutron-rich nucleus ^{43}S were performed by applying the recoil-distance method on fast rare-isotope beams in conjunction with the Gamma-Ray Energy Tracking In-beam Nuclear Array, and new data based on γγ coincidences and lifetime measurements resolve a doublet of (3/2^{-}) and (5/2}) states at low excitation energies.

TL;DR: In this paper, the odd-odd nucleus 30Na was studied via a one-proton, oneproton-one-neutron and one-neurons removal reaction using an intermediate-energy 31Mg, 32Mg and 31Na radioactive ion beam, respectively.

TL;DR: In this paper, the authors reported the first lifetime measurement of excited states in 21O, finding τ 1 / 2 + = 420 − 32 + 35 (stat) − 12 + 34 (sys) ps.
