Determination of dipole and quadrupole polarizabilities of Mg+ by fine-structure measurements in high-L n=17 Rydberg states of magnesium

摘要

Fine-structure intervals between n = 17 Rydberg states of magnesium with 6 <= L >= 11 were measured using the resonant excitation Stark ionization spectroscopy technique. Comparing the measured intervals with the long-range polarization model determines the dipole and quadrupole polarizabilities of Mg+ to be alpha(1)=35.00(5)a(0)(3) and alpha(2)=222(54)a(0)(5), respectively.
