[paper] Interplay between nuclear shell evolution and shape deformation revealed by the magnetic moment of 75Cu

Interplay between nuclear shell evolution and shape deformation revealed by the magnetic moment of 75Cu Y. Ishikawa et al. Nature Physics (2019) DOI: 10.1038/s41567-018-0410-7 Exotic nuclei are characterized by having a number of neutrons (or protons) in excess relative to stable nuclei. Their shell structure, which represents single-particle motion in a nucleus, may vary due… Read More [paper] Interplay between nuclear shell evolution and shape deformation revealed by the magnetic moment of 75Cu

[paper] Isoscalar Spin Matrix Elements in s–d Shell Nuclei

Isoscalar Spin Matrix Elements in s–d Shell Nuclei by Akito Arima and Wolfgang Bentz doi: 10.7566/JPSCP.23.012011 The quenching of isovector spin matrix elements in s–d shell nuclei is well established experimentally as well as theoretically [1,2,3]. The isoscalar spin gyromagnetic ratios gsIS of nuclei with one nucleon or hole outside of LS closed shells are… Read More [paper] Isoscalar Spin Matrix Elements in s–d Shell Nuclei

Isoscalar and isovector spin response in sd-shell nuclei

The spin magnetic-dipole transitions and the neutron-proton spin-spin correlations in sd-shell even-even nuclei with N=Z are investigated by using shell-model wave functions taking into account enhanced isoscalar (IS) spin-triplet pairing as well as the effective spin operators. It was shown that the IS pairing and the effective spin operators gives a large quenching effect on… Read More Isoscalar and isovector spin response in sd-shell nuclei

Probing Sizes and Shapes of Nobelium Isotopes by Laser Spectroscopy

Until recently, ground-state nuclear moments of the heaviest nuclei could only be inferred from nuclear spectroscopy, where model assumptions are required. Laser spectroscopy in combination with modern atomic structure calculations is now able to probe these moments directly, in a comprehensive and nuclear-model-independent way. Here we report on unique access to the differential mean-square charge… Read More Probing Sizes and Shapes of Nobelium Isotopes by Laser Spectroscopy
