Abstract

A novel technique combining the advantages of the laser-rf double-resonance scheme and fast-beam collinear laser spectroscopy has been applied to a detailed study of the hyperfine structure of U235 I I. The experimental results are analyzed with use of ab initio Dirac-Fock calculations of the reduced radial parameters of relativistic hyperfine-structure theory. The analysis results in a new value for the nuclear dipole moment μ(U235)=0.38(3)μN and a determination of the spin density a10(7s)=2880(75) MHz of the 7s electron.
