“…Resonance ionization spectroscopy is also being used to measure nuclear moments and charge radii: It has been applied combined with collinear laser spectroscopy [93,94], in a gas cell [95], after deposition and laser ablation from a beam catcher as applied by the COMPLIS collaboration [96], e.g. for the tin isotopes [97,98], or directly inside the hot-source (in order of decreasing resolution). The last method offers the lowest resolution but is extremely sensitive and the resolution is often still sufficient for the heavy isotopes that exhibit large field shifts and large hyperfine splittings.…”

Atomic physics techniques for the determination of ground-state properties of radioactive isotopes are very sensitive and provide accurate masses, binding energies, Q-values, charge radii, spins, and electromagnetic moments. Many fields in nuclear physics benefit from these highly accurate numbers. They give insight into details of the nuclear structure for a better understanding of the underlying effective interactions, provide important input for studies of fundamental symmetries in physics, and help to understand the nucleosynthesis processes that are responsible for the observed chemical abundances in the Universe. Penning-trap and and storage-ring mass spectrometry as well as laser spectroscopy of radioactive nuclei have now been used for a long time but significant progress has been achieved in these fields within the last decade. The basic principles of laser spectroscopic investigations, Penning-trap and storage-ring mass measurements of short-lived nuclei are summarized and selected physics results are discussed. † going to cryogenic temperatures, or enhancing the induced signal by using higher charge states and/or longer accumulation times. Ideal applications for this method are mass measurements of super-heavy element (SHE) isotopes for nuclear structure studies as they are performed at SHIPTRAP [25,26]. SHE are produced in minuscule quantities, and typically have half-lives of hundreds of milliseconds to a few seconds. A proof-ofprinciple experiment is planned at the TRIGA reactor facility TRIGA-TRAP at Mainz University [27] and applications for HITRAP with highly charged ions are foreseen [28]. Requirements for Mass Measurements of Radioactive IonsThe specific requirements for the mass measurements of radioactive ions stem from the parameters of the ions themselves. For example the required sensitivity (depending on the production yield) and measurement speed (depending on the half-life) as well as the envisaged application which dictates the required precision. In order to be meaningful, all measurements should deliver reliable data, hence precise and accurate. The physics requirements can be categorized with the corresponding relative precision as follows:• nuclear structure, δm/m ≈ 1 × 10 −7• nuclear astrophysics, δm/m ≈ 1 × 10 −7/−8 • test of fundamental symmetries, neutrino physics, δm/m ≈ 1 × 10 −8/−9

“…1 we display the self-consistent RHB model results for the charge isotope shifts and the differences between the radii of the neutron and proton density distributions of Sn isotopes. The Gogny interaction D1S [28] is used in the pairing channel, and the radii calculated with the DD-ME1 interaction, and with two standard non-linear effective interactions NL1 [29] and NL3 [30], are shown in comparison with available empirical data [31,32,33]. Although the charge radii calculated with all three effective interactions are in very good agreement with experimental data, only DD-ME1 quantitatively reproduces the evolution of the neutron skin.…”

The isotopic dependence of the excitation energies of the pygmy dipole resonance (PDR) is analyzed in the framework of the self-consistent relativistic Hartree-Bogoliubov (RHB) model and the relativistic quasiparticle random-phase approximation (RQRPA). The DD-ME1 density-dependent meson-exchange interaction is used in the effective mean-field Lagrangian, and pairing correlations are described by the pairing part of the finite-range Gogny interaction D1S. Model calculations reproduce available experimental data on charge radii, the neutron skin, neutron separation energies, and excitation energies of isovector giant dipole resonances in Ni, Sn and Pb nuclei. In all three isotopic chains the one-neutron separation energies decrease with mass number much faster than the excitation energies of the PDR. As a result, already at moderate proton-neutron asymmetry the PDR peak energy is calculated above the neutron emission threshold. This result has important implications for the observation of the PDR in (gamma,gamma') experiments.Comment: 9 pages, 4 figures, accepted for publication in Phys. Lett.

We compare them to the available experimental information obtained from various methods including laser and muonic atoms spectroscopy [18][19][20][21][22].We also compare between results with different theoretical force of Skyrme calculations. The SkM* is the closer force to the experimental data.…”

Hartree-Fock calculations for even-even Tin isotopes usingSkyrme density dependent effective nucleon-nucleon interaction arediscussed systematically. Skyrme interaction and the general formulafor the mean energy of a spherical nucleus are described. The chargeand matter densities with their corresponding rms radii and thenuclear skin for Sn isotopes are studied and compared with theexperimental data. The potential energy curves obtained withinclusion of the pairing force between the like nucleons in Hartree-Fock-Bogoliubov approach are also discussed.
