“…Finally, the hyperfine structure anomaly for isotopes and isomers with s 1 2 , d 5 2 , and h 11 2 states was evaluated and a linear relationship observed for all nuclear states except s 1 2 . This is in accordance with the Moskowitz-Lombardi rule, being established in the mercury region of the nuclear chart, and was observed in all four atomic and ionic levels that were investigated [71].…”

Over three and a half decades of collinear laser spectroscopy and the COL-LAPS setup have played a major role in the ISOLDE physics programme. Based on a general experimental principle and diverse approaches towards higher sensitivity, it has provided unique access to basic nuclear properties such as spins, magnetic moments and electric quadrupole moments as well as isotopic variations of nuclear mean square charge radii. While previous methods of outstanding sensitivity were restricted to selected chemical elements with special atomic properties or nuclear decay modes, recent developments have yielded a breakthrough in sensitivity for nuclides in wide mass ranges. These developments include the use of bunched beams from the radiofrequency quadrupole cooler-buncher ISCOOL, which allows a suppression of background by several orders of magnitude. Very recently, the combination of collinear laser spectroscopy with the principle of laser resonance ionisation took shape in the new CRIS setup, providing a very selective and efficient detection of optical resonance. We outline the basic experimental developments and discuss important results on nuclei or chains of isotopes in different mass ranges.

“…For the recent laser experiments of Cd isotopes in an ionic state [46] V zz has been recalculated with the multi-configuration Dirac-Hartree-Fock [47] approach and found to be about 14% higher than the old result would suggest. More recent experimental and theoretical work for the 3 P 2 state of the Cd isotopes [48] has completely confirmed this finding. For the case of 67 Zn there is also some evidence that the old reference value could be wrong.…”

The effect of the Gaunt interaction on the electricfield gradient M Pernpointner -Hyperfine local probe study of alkalineearth manganites SrMnO3 and BaMnO3 J N Gonçalves, V S Amaral, J G Correia et al.- Spin-orbit Motivation. -Precise nuclear quadrupole moments (Q) are essential not only for a detailed understanding of nuclei but also for any quantitative analysis of quadrupole interaction measurements in solids, molecules, or atoms. Normally only the product of Q with the electric-field gradient (EFG, major component V zz ) created by the electronic environment, the nuclear quadrupole coupling constant, ν Q = eQV zz /h, is experimentally available. Thus for determination of reliable values of V zz an accurate number for Q is needed. The EFG, however, is one of a few experimentally available direct measures of the charge distribution in matter. It essentially contains the information on the asymmetry in the local p- (or d-) orbitals, a property intimately related to chemical bonding.In order to obtain a reliable value for Q, on the other hand, V zz has to be calculated with a highly accurate theoretical method for at least one system where ν Q is well known. Quantum-mechanical methods have been generally quite successful in the interpretation of atomic and more recently also molecular data [1]. With the advent of density functional (DF) methods a possibility to routinely calculate EFGs in solids became available and for several

“…This allowed us to extend the range of measurements up to 130 Cd and altogether cover the complete sdgh shell with the exception of 99 Cd. More details on the collinear spectroscopy on Cd I [33] and Cd II [34,35] are provided in previous publications in which the nuclear moments [33,34] and the isomer shifts [35] are addressed.…”

From Calcium to Cadmium: Testing the Pairing Functional through Charge Radii Measurements of Cd100−130

Differences in mean-square nuclear charge radii of ^{100-130}Cd are extracted from high-resolution collinear laser spectroscopy of the 5s ^{2}S_{1/2}→5p ^{2}P_{3/2} transition of the ion and from the 5s5p ^{3}P_{2}→5s6s ^{3}S_{1} transition in atomic Cd. The radii show a smooth parabolic behavior on top of a linear trend and a regular odd-even staggering across the almost complete sdgh shell. They serve as a first test for a recently established new Fayans functional and show a remarkably good agreement in the trend as well as in the total nuclear charge radius.
