Description
The nuclear radius is one of the fundamental properties of the atomic nucleus. While the direct measurement is not always possible, one can infer its size by measuring other observables.
Recent theoretical studies by Bonnard and collaborators have put in evidence the role of the large radius of low-l orbits in a main nuclear shell in determining the nuclear radius and its evolution when varying their occupancy.
Isotope shifts allow to follow the evolution of radii with increasing the neutron number far from stability.
Another sensitive tool to study these properties is the measurement of the differences in excitation energy of mirror nuclei in different mass regions.
Recent experimental studies for both isotope shifts and mirror energy differences can be reproduced by shell model calculations that include the effect of low-l (halo) single-particle orbitals. They will be discussed in this presentation.
