Collinear laser spectroscopy is performed on the nickel isotopes 58−68,70Ni, using a time-resolved photon counting system. From the measured isotope shifts, nuclear charge radii Rc are extracted and compared to theoretical results. Three ab initio approaches all employ, among others, the chiral interaction NNLOsat, which allows an assessment of their accuracy. We find agreement with experiment in differential radii δ⟨r2c⟩ for all employed ab initio methods and interactions, while the absolute radii are consistent with data only for NNLOsat. Within nuclear density functional theory, the Skyrme functional SV-min matches experiment more closely than the Fayans functional Fy(Δr,HFB).

Nuclear moments of indium isotopes reveal abrupt change at magic number 82

Vernon, A. R.; Garcia Ruiz, R. F.; Miyagi, T.; Binnersley, C. L.; Billowes, J.; Bissell, M. L.; Bonnard, J.; Cocolios, T. E.; Dobaczewski, J.; Farooq-Smith, G. J.; Flanagan, K. T.; Georgiev, G.; Gins, W.; de Groote, R. P.; Heinke, R.; Holt, J. D.; Hustings, J.; Koszorús, Á.; Leimbach, D.; Lynch, K. M.; Neyens, G.; Stroberg, S. R.; Wilkins, S. G.; Yang, X. F.; Yordanov, D. T. (Nature Publishing Group, 2022)

In spite of the high-density and strongly correlated nature of the atomic nucleus, experimental and theoretical evidence suggests that around particular ‘magic’ numbers of nucleons, nuclear properties are governed by a ...

We report on a set of high-precision measurements of nuclear binding and excitation energies, as well as nuclear spins, magnetic dipole and electric quadrupole moments of neutron-rich silver isotopes, 113−123Ag. The ...
Measurement and microscopic description of odd-even staggering of charge radii of exotic copper isotopes

Y.; Yang, X. F. (Nature Publishing Group, 2020)

Nuclear charge radii globally scale with atomic mass number A as A1∕3, and isotopes with an odd number of neutrons are usually slightly smaller in size than their even-neutron neighbours. This odd-even staggering, ubiquitous ...
