13. Simple models of nuclear moments

Piet Van Isacker (GANIL)

13/05/2025 16:20

Nuclear magnetic dipole and electric quadrupole moments are sensitive probes of the single-particle as well as the collective properties of nuclei. In this talk I review the predictions of the shell model and the interacting boson model as regards nuclear moments. The emphasis is on elementary properties that can be understood from symmetry-based principles such as, for example, the...

32. Nuclear moments in projectile fragmentation. Lessons from the past with a sight to the future.

Georgi Georgiev (CSNSM, Orsay, France)

The nuclear electromagnetic moments provide an essential insight into the structure of the nuclei. They are of special interest for exotic regions in the nuclear chart where new shell effects or rapid modifications of the nuclear structure could be expected. The magnetic dipole moments provide a fingerprint of the single-particle properties of the nuclear wave function while the electric...

20. g-factor measurements of the 171keV $(2^{-})$ and 375keV $(4^{-})$ isomeric states of $^{98}Y$

David Friant (Institut Laue-Langevin / CEA Saclay)

The shape transition from spherical nuclear states $(N<59)$ towards deformed states $(N>59)$ is of high interest as it provides fertile ground for the validation of nuclear models. The $N=59$ nuclide $^{98}$Y is located precisely at this transition point and is characterized by shape coexistence of several nuclear deformations.
