Systematic measurements of the bohr-weisskpf effect at isolde
1992
The hyperfine anomaly gives an insight into the coupling of spin and orbital magnetic moments in the nucleus. More precisely, the nuclear magnetization is expressible through the nuclear wave functions with which is tested not only the magnetic moment operator, but also the tensor product [s×C2]1. The experiment can then be expected to be of value in testing the nuclear structure theory. The greatest value of these measurements is gained when these are made systematically over a large number of isotopes. We propose to initiate a program at ISOLDE to measure the hyperfine anomaly systematically in the heavy alkali elements. The experimental setup to achieve, in particular, a precise measurem…
Large Odd-even Radius Staggering In The Very Light Platinum Isotopes From Laser Spectroscopy
1999
Laser spectroscopy measurements have been carried out on very-neutron-deficient platinum isotopes with the COMPLIS experimental setup. Using the ${5d}^{9}{6s}^{3}{D}_{3}\ensuremath{\rightarrow}{5d}^{9}{6p}^{3}{P}_{2}$ optical transition, hyperfine spectra of ${}^{182,181,180,179,178}\mathrm{Pt}$ and ${}^{183}{\mathrm{Pt}}^{m}$ were recorded for the first time. The variation of the mean square charge radius between these nuclei, the magnetic moments of the odd isotopes, and the quadrupole moment of ${}^{183}{\mathrm{Pt}}^{m}$ were thus measured. A large deformation change between ${}^{183}{\mathrm{Pt}}^{g}$ and ${}^{183}{\mathrm{Pt}}^{m},$ an odd-even staggering of the charge radius, and a d…
Nuclear Moments and Deformation Change inA184ug,mfrom Laser Spectroscopy
1997
Resonance ionization spectroscopy (RIS) was performed on desorbed Au, and the complete hyperfine spectrum of both isomeric and ground states of the short lived 184Au nucleus has been recorded from the 5d106s S1y2 ! 5d106p P3y2 optical transition. The nuclear moments of both states and the mean square charge radius changes were measured. The magnetic moments were determined to be m 184g I5 12.07s2dmN and m I2 11.44s2dmN and the spectroscopic quadrupole moments to be Q 184g s 14.65s26db and Q184m s 11.90s16d b. A difference in the mean square charge radius dkr2 c l184g,184m 20.036s3d fm2 was found. [S0031-9007(97)03992-6]
