“…3/2 level at 40114.01 cm −1 . This was achieved using an injection-locked titaniumsapphire laser system developed by the Johannes Gutenberg-Universität Mainz and the University of Jyväskylä [39,40]. Through pulsed amplification of 749 nm continuous-wave seed light produced by an M-squared SolsTis titaniumsapphire laser, narrow-band pulsed laser light was produced at a repetition rate of 1 kHz.…”

Nuclear spins and precise values of the magnetic dipole and electric quadrupole moments of the ground states of neutron-rich 73-78 Cu isotopes were measured using the Collinear Resonance Ionization Spectroscopy (CRIS) experiment at the CERN On-Line Isotope Mass Separator (ISOLDE) facility. The nuclear moments of the less exotic 73,75 Cu isotopes were remeasured with similar precision, yielding values that are consistent with earlier measurements. The moments of the odd-odd isotopes, and 78 29 Cu (N = 49) in particular, are used to investigate excitations of the assumed doubly magic 78 Ni core through comparisons with large-scale shell-model calculations. Despite the narrowing of the Z = 28 shell gap between N ∼ 45 and N = 50, the magicity of Z = 28 and N = 50 is restored toward 78 Ni. This is due to weakened dynamical correlations, as clearly probed by the present moment measurements.

“…Since is in the blue wavelength regime, we generated the second harmonic intra-cavity, using a beta barium borate (BBO) crystal. For measuring hyperfine spectra we can alternatively produce by an injection-locked Ti:sapphire laser with a Fourier-limited linewidth of for the spectroscopy transition [ 21 , 22 ], seeded by an external cavity diode laser (master ECDL). In this case the second harmonic was generated outside the cavity by focusing the laser into a BBO crystal in simple single-pass transmission.…”

High-resolution laser resonance ionization spectroscopy of $$^{143-147}$$Pm

We present the results of high-resolution laser spectroscopy of the long-lived radioactive isotopes 143−147 Pm. The hyperfine structures and isotope shifts in two different atomic ground-state transitions at 452 nm and 468 nm were probed by in-source laser spectroscopy at the RISIKO mass separator in Mainz, using the PI-LIST ion source. From the hyperfine coupling constants the nuclear magnetic dipole and electric quadrupole moments for 143−147 Pm were derived, and the measured isotope shifts allowed the extraction of changes in nuclear mean square charge radii.

Analytic response relativistic coupled-cluster theory: the first application to indium isotope shifts

et al. 2020

View full text Add to dashboard Cite

With increasing demand for accurate calculation of isotope shifts of atomic systems for fundamental and nuclear structure research, an analytic energy derivative approach is presented in the relativistic coupled-cluster (CC) theory framework to determine the atomic field shift and mass shift (MS) factors. This approach allows the determination of expectation values of atomic operators, overcoming fundamental problems that are present in existing atomic physics methods, i.e. it satisfies the Hellmann-Feynman theorem, does not involve any non-terminating series, and is free from choice of any perturbative parameter. As a proof of concept, the developed analytic response relativistic CC theory has been applied to determine MS and field shift factors for different atomic states of indium. High-precision isotope-shift measurements of -104 127 In were performed in the 246.8 nm (5p 2 P 3/2  9s 2 S 1/2 ) and 246.0 nm (5p 2 P 1/2  8s 2 S 1/2 ) transitions to test our theoretical results. An excellent agreement between the theoretical and measured values is found, which is known to be challenging in multi-electron atoms. The calculated atomic factors allowed an accurate determination of the nuclear charge radii of the ground and isomeric states of the -104 127 In isotopes, providing an isotone-independent comparison of the absolute charge radii.
