“…The target and the ionizing tube were heated to around 2000 0 C. The accelerated ions (up to 40 kV) were mass separated by the high resolution separator (HRS). The gas-filled Paul trap (ISCOOL) [28,29] was used for cooling and bunching of the ions. Multiple bunches spaced by 90 ms were generated after each proton pulse.…”

Background: Ground-state spins and magnetic moments are sensitive to the nuclear wave function, thus they are powerful probes to study the nuclear structure of isotopes far from stability.Purpose: Extend our knowledge about the evolution of the 1/2 + and 3/2 + states for K isotopes beyond the N = 28 shell gap.Method: High-resolution collinear laser spectroscopy on bunched atomic beams.Results: From measured hyperfine structure spectra of K isotopes, nuclear spins and magnetic moments of the ground states were obtained for isotopes from N = 19 up to N = 32. In order to draw conclusions about the composition of the wave functions and the occupation of the levels, the experimental data were compared to shell-model calculations using SDPF-NR and SDPF-U effective interactions. In addition, a detailed discussion about the evolution of the gap between proton 1d 3/2 and 2s 1/2 in the shell model and ab initio framework is also presented.

Abstract. The self-consistent model, developed previously to describe phonon coupling (PC) effects in magnetic moments of odd magic and semi-magic nuclei, is extended to quadrupole moments. It is based on the theory of finite Fermi systems with the use of the perturbation theory in g 2 L , where g L is the vertex creating the L-phonon. Accounting for the phonon tadpole diagrams is an important ingredient of this model. The calculation scheme is based on the Fayans energy density functional DF3-a and does not contain any adjusted parameters. The odd In and Sb isotopes are considered, which are the proton-odd neighbors of even tin nuclei. The 2 + 1 phonon is taken into account which quadrupole moment is one ingredient of the calculation scheme. The corresponding values were found by us previously. Two main PC corrections, due to the phonon Z-factor and due to the phonon-induced interaction, have opposite signs and cancel strongly each other, leaving room for other 'small' corrections, so that the resulting PC correction is much lower than the absolute values of each of two main ones. However, it remains noticeable, making the overall agreement with the data significantly better.

Post-accelerated isomerically purified radioactive beams, available at the CERN On-Line Isotope Mass Separator facility using the resonant ionization laser technique, have been used to study the Coulomb excitation of the I π = 3 − state in 70 Cu (Z = 29, N = 41). While first results using a I π = 6 − beam were reported previously, the present complementary experiment allows us to complete the study of the multiplet of states (3 − , 4 − , 5 − , 6 − ) arising from the π 2p 3/2 ν1g 9/2 configuration. Besides the known γ -ray transition deexciting the 4 − state, a ground-state γ ray of 511(3) keV was observed for the first time and was unambiguously associated with the 5 − state deexcitation. This observation fixes the energy, spin, and parity of this state, completing the low-energy level scheme of 70 Cu. B(E2) values for all possible E2 transitions within the multiplet were determined. A comparison with large-scale shell model calculations using different interactions and valence spaces shows the importance of proton excitation across the Z = 28 shell gap and the role of the 2d 5/2 neutron orbital.
