Laser spectroscopy of neutron-rich Hg isotopes: Illuminating the kink and odd-even staggering in charge radii across the shell closure

T. Day Goodacre, A. V. Afanasjev, A. E. Barzakh +41

The mean-square charge radii of Hg () have been studied for the first time and those of Hg () remeasured by the applicat…

Consistency of nucleon-transfer sum rules in well-deformed nuclei

B. P. Kay, J. P. Schiffer, S. J. Freeman +8

Nucleon-transfer sum rules have been assessed via a consistent reanalysis of cross-section data from neutron-adding (,) and -removing (,) reactions on well-deformed iso…

Role of chiral two-body currents in Li magnetic properties in light of a new precision measurement with the relative self-absorption technique

U. Friman-Gayer, C. Romig, T. Hüther +18

A direct measurement of the decay width of the excited state of Li using the relative self-absorption technique is reported. Our value of $Γ_{γ, 0^+_1 \to 1^+_1} = 8.17…

Coulomb excitation of the , mirror pair

J. Henderson, G. Hackman, P. Ruotsalainen +23

Background: Electric-quadrupole () strengths relate to the underlying quadrupole deformation of a nucleus and present a challenge for many nuclear theories. Mirror nuclei in th…

The observation of vibrating pear shapes in radon nuclei: update

P. A. Butler, L. P. Gaffney, P. Spagnoletti +41

There is a large body of evidence that atomic nuclei can undergo octupole distortion and assume the shape of a pear. This phenomenon is important for measurements of electric-dipol…

Evolution of Octupole Deformation in Radium Nuclei from Coulomb Excitation of Radioactive Ra and Ra Beams

P. A. Butler, L. P. Gaffney, P. Spagnoletti +40

There is sparse direct experimental evidence that atomic nuclei can exhibit stable pear shapes arising from strong octupole correlations. In order to investigate the nature of octu…
