Collinear fast-beam-laser and rf-laser double-resonance spectroscopy have been carried out in 235U ii, allowing a detailed study of the hyperfine structure (hfs) of the three low odd configurations 5f3(7S2 + 6d7s + 6d2). Intermediate coupling wave functions, using parametric fitting, have been determined, allowing a parameterization of the hyperfine interaction. Ab initio Dirac–Fock calculations combined with this parameterization of our experimental data have allowed an analysis of the hfs of 235U ii, resulting in a new value for the magnetic-dipole moment μI = −0.38(3) nm and a spin density a7s10 = −2880(75) MHz of the 7s electron.
