| Popis: |
The laser-rf double-resonance technique has been used to study the hyperfine structure (hfs) of the excited $3{d}^{4}4s^{4}D$ levels of $^{15}\mathrm{V}$ in a continuation of earlier atomic-beam magnetic-resonance studies of the lower levels. The new results make it possible for the first time to distinguish clearly between the contact hfs due to the $4s$ electron and that due to core polarization associated with the $3d$ electrons. The values found for the radial hfs integrals from a systematic analysis of both the new and earlier results are compared with the relativistic Hartree-Fock values of Lindgren and Ros\'en. The magnetic octopole hfs interaction is measured for one level. Hyperfine constants and lifetime information, deduced from laser-fluorescence studies, are presented for the levels $3{d}^{4}4p^{4}P_{\frac{5}{2},\frac{3}{2},\frac{1}{2}}^{o}$ at \ensuremath{\sim}25000 ${\mathrm{cm}}^{\ensuremath{-}1}$ exitation. |
