TL;DR: The ratio of neutron to proton contributions to the 2(1)+ state is found close to the N/Z ratio, demonstrating a strong N = 14 shell closure in the vicinity of the neutron drip line.

TL;DR: In this article, the quenching of the N=20 shell gap in neutron-rich nuclei is investigated by studying the single-particle structure of 27Ne via neutron transfer using a 26Ne beam.
Journal ArticleDOI

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.
Journal ArticleDOI
