Sternheimer free determination of the47Ti nuclear quadrupole moment from hyperfine structure measurements

  • Published:
Zeitschrift für Physik D Atoms, Molecules and Clusters

Abstract

The hyperfine structure (hfs) of 12 metastable states of47Ti has been measured by laser induced fluorescence. 11 of these states have been measured additionally very precisely by a laser-rf double resonance method. Taking into account results of earlier hfs measurements, the hfs of altogether 17 fine structure states has been analyzed by the simultaneous parametrization of the one- and two-body interactions in the atomic hfs for the model space (3d+4s)N+2 (N=2). This gives 16 parameters for the magnetic dipole interaction and 12 parameters for the electric quadrupole interaction. From the model space parameters, obtained from the hfs fit, the nuclear quadrupole momentQ(47Ti)=0.303(24b), has been evaluated at the first time; it is free of Sternheimer corrections up to second order.
