We review major experiments and results obtained by the on-line low temperature nuclear orientation method at the NICOLE facility at ISOLDE, CERN since the year 2000 and highlight their general physical impact. This versatile facility, providing a large degree of controlled nuclear polarization, was used for a long-standing study of magnetic moments at shell closures in the region Z=28, N=28-50 but also for dedicated studies in the deformed region around A∼180. Another physics program was conducted to test symmetry in the weak sector and constrain weak coupling beyond V-A. Those two programs were supported by careful measurements of the involved solid state physics parameters to attain the full sensitivity of the technique and provide interesting interdisciplinary results. Future plans for this facility include the challenging idea of measuring the beta-gamma-neutron angular distributions from polarized beta delayed neutron emitters, further test of fundamental symmetries and obtaining nuclear structure data used in medical applications. The facility will also continue to contribute to both the nuclear structure and fundamental symmetry test programs.

“…Indeed, the odd-A 29 Cu isotopes can be described as a single proton coupled to an even-A 28 Ni core and their magnetic dipole moment should in principle be defined by the latter particle only. The copper isotopes have therefore been extensively studied [11,12,13,14,15,16,17]. The magnetic moments from N = 30 up to N = 40 depart strongly from the Schmidt moment of a single proton in the 1p 3/2 orbital [13]; this trend continues while approaching N = 28.…”

Magnetic Dipole Moment ofCu57,59Measured by In-Gas-Cell Laser Spectroscopy

In-gas-cell laser spectroscopy study of the 57,59,63,65 Cu isotopes has been performed for the first time using the 244.164 nm optical transition from the atomic ground state of copper. The nuclear magnetic dipole moments for 57,59,65 Cu relative to that of 63 Cu have been extracted. The new value for 57 Cu of µ( 57 Cu) = +2.582(7)µN is in strong disagreement with the previous literature value but in good agreement with recent theoretical and systematic predictions.PACS numbers: 21.10. Ky, 27.40.+z, 27.50.+e, 42.62.Fi With more than 3000 nuclei known so far, the present nuclear chart offers a vast landscape to study mesoscopic systems. Many of these nuclei cannot be described by ab initio calculations and theory uses models based on a fundamental or phenomenological approach in order to describe observables of isotopes yet to discover. The confrontation of experimental data with the theoretical predictions does not only allow for fine tuning of theory but also for discovering new aspects of the interactions at work in the atomic nucleus. This is especially the case when studying isotopes with extreme proton-toneutron ratios. In nuclear structure, the identification of the magic numbers 2, 8, 20, 28, 50, 82, 126 [1] is the foundation for the shell model of the nucleus. While these magic numbers are well established in nuclei close to the valley of β-stability, their universality is strongly questioned [2].Of special interest is the magic number 28 as it is the smallest magic number issued from the spin-orbit interaction added to the nuclear potential. Both the N = 28 isotones [3,4] and the nickel (Z = 28) isotopes [5,6] are under intensive investigation to probe their magic character. With N = Z = 28, 56 Ni is expected to be doubly magic. While it displays a high 2 + 1 excited state in comparison to the other nickel isotopes [5] and a sudden change in the two-neutron and two-proton separation energies [7], both characteristic of a doubly magic nucleus, the evolution of the transition strength B(E2) and the behavior of the nuclei in the vicinity point towards particle excitations across the shell gaps and a breaking of this magic core [8,9,10].The nuclear magnetic dipole moment is a very sensitive tool to study the nuclear structure in the vicinity of magic nuclei.

“…This confirms the fact that, even far from the beta-stability valley, these nuclei do not lose a spherical shape. The situation is totally different around the copper chain, for which the magnetic moments of several new isotopes were recently measured [38]. As a result, the magnetic moments of a long chain of nuclei that contain an odd proton and in which the sequence of even-even cores (nickel isotopes) extends from 56 Ni to 78 Ni proved to be known, albeit with different accuracies.…”

Dipole magnetic moments of more than 100 odd spherical nuclei are calculated within the theory of finite Fermi systems. For the effective interaction of nucleons within the theory of finite Fermi systems, use is made of a version that takes into account nuclear-medium-modified amplitudes for the exchange of one pion and one rho meson. A new tensor local charge ζ t is incorporated in the theory of finite Fermi systems in addition to the known orbital (ζ l ) and spin (ζ s ) local charges. Good agreement with experimental data, at a level of 0.1 to 0.2µ N , is obtained for the overwhelming majority of the nuclei considered here. Several cases of a significant discrepancy with experimental data, at a level of 0.3 to 0.5µ N , are revealed. Possibilities for removing these discrepancies are discussed. A detailed comparison with known results obtained within the multiparticle shell model is performed for 2p-to 1f -shell nuclei. Cases where the standard theory of finite Fermi systems must be extended by taking into account multiparticle configurations are found. Magnetic moments are analyzed for a number of long isotopic chains. Several new experimental values of magnetic moments for copper isotopes far from the beta-stability valleys are known. For the example of the copper-isotope chain, it is shown how the emergence of a deformation in the ground state of a nucleus can be revealed on the basis of a systematic analysis of magnetic moments.
