description

The hyperfine spectra of the 5s4d3D1-5s20f, 5s4d3D2-5s23f, and 5s 4d3D3-5s32f transitions of87Sr (I=9/2) have been measured by collinear fast beam laser spectroscopy. The structure in the upper configurations is highly perturbed by fine structure splitting that is of comparable size to the hyperfine interaction energy. These perturbations can be adequately treated with conventional matrix diagonalization methods, using the 5s-electron magnetic dipole interaction terma5s and the unperturbed fine structure splittings as input parameters. Additionally, hyperfine constants for the lower 5s4d3D configurations, including theA- andB-factors and a separation of the individuals- andd-electron contributions to these factors, are derived.
