Nuclear charge radii of (21-32)Mg.
Charge radii of all magnesium isotopes in the sd shell have been measured, revealing evolution of the nuclear shape throughout two prominent regions of assumed deformation centered on (24)Mg and (32)Mg. A striking correspondence is found between the nuclear charge radius and the neutron shell structure. The importance of cluster configurations towards N=8 and collectivity near N=20 is discussed...
متن کاملGarvey-Kelson Relations for Nuclear Charge Radii
The Garvey-Kelson relations (GKRs) are algebraic expressions originally developed to predict nuclear masses. In this letter we show that the GKRs provide a fruitful framework for the prediction of other physical observables that also display a slowly-varying dynamics. Based on this concept, we extend the GKRs to the study of nuclear charge radii. The GKRs are tested on 455 out of the approximat...
متن کاملCharge radii of light and heavy mesons
We calculate the electromagnetic (EM) form factors of the pseudoscalar mesons in the light-front framework. Specifically, these form factors are extracted from the relevant matrix elements directly, instead of choosing the Breit frame. The results show that the charge radius of the meson is related to both the first and second longitudinal momentum square derivatives of the momentum distributio...
متن کاملStaggering of the nuclear charge radii in a superfluid model with good particle number.
A simple superfluid model with an effective four body interaction of monopole pairing type is used to explain the staggering of the charge radii in the isotope chains. The contribution of deformation and of the particle number projection are analyzed for the Sn isotopes. Good results are obtained for the staggering parameters and neutron pairing energies. PACS numbers: 21.10.Dr, 21.10.Ft, 21.30...
متن کاملMeasurement of the Charge Radii of Li using Laser Spectroscopy
The radioactive isotopes of lithium have been the subject of numerous investigations, particularly after the discovery of the exotic Halo nucleus Li in 1985 [1]. Matter radii, excited states and electromagnetic moments have been determined. But the charge distribution inside the nuclei and how it is affected by the increasing number of neutrons is still an open question. Charge radii from cross...
