Proton-neutron pairing is an exotic type of pairing between two different particles, only existing in N Z nuclei. It was studied in the middle of the f7/2 shell using the 48Cr(p,3He)46V two-nucleon transfer reaction in order to investigate the competition between the …

Low-energy multi-step Coulomb excitation measurements have been performed to study the structure of low-lying excitations in the zirconium isotopes, which are particularly interesting as, in recent years, evidence has come to light that they are excellent cases for exhibiting shape evolution and …

The isotopic mass region at the intersection of Z = 20 and N = 28 magic numbers presents a unique opportunity to constrain both the diverging neutron shell structure approaching 54Ca, the breakdown of the N = 28 shell closure, and the …

The disappearance of the N=20 shell closure, the so-called “island of inversion”, around 32Mg is one of the most striking examples of the strength of nucleon-nucleon correlations. In this region, the quadrupole-deformed intruder configuration (based on a multi-particle multi-hole configuration) becomes the …
