Le résumé fourni par la source

The rapid structural evolution and increase in collectivity seen in the N = 40 region of the nuclear chart arise due to the weakening of the sub-shell closure at N = 40 and acts as a key testing ground for various theoretical models. While 68Ni is a clear exception showing signs of double magicity, the removal of protons from the f7/2 proton orbital increases deformation in the neighboring Fe and Cr isotopic chains. A high-statistics β-decay study of 68Mn was performed at the TRIUMF-ISAC facility to elucidate the low-lying structure of 68Fe. Detailed spectroscopy was performed using the GRIFFIN spectrometer. Preliminary results confirm previously identified γ-ray transitions in 68Fe, 68Co and 68Ni, while also indicating the presence of several new transitions.
