摘要：

We report on the spectroscopy of highly excited strontium ions after resonant multistep laser excitation. The states observed belonged to the ns (26 less-than-or-equal-to n less-than-or-equal-to 79), nd (25 less-than-or-equal-to n less-than-or-equal-to 83), nf (28 less-than-or-equal-to n less-than-or-equal-to 86) and ng (30 less-than-or-equal-to n less-than-or-equal-to 81) series of Sr+. A least squares fit has been applied to determine the quantum defects and their linear energy dependence in each series, together with the ionisation limit of Sr+. The analysis of our data lead to a revised value for this ionisation limit of 88965.18 +/- 0.02 cm-1, with respect to the ground state of the Sr+ ion. Analysis of the non core-penetrating ng states yielded experimental values for the dipole and quadrupole polarizability of Sr++, which are in satisfactory agreement with previous calculations.
