Phys. Rev. A 78, 062510 (2008) [14 pages]Microwave spectroscopy of high- L n=10 Rydberg states of argonReceived 6 October 2008; published 31 December 2008 Twenty-one fine-structure intervals between n=10 argon Rydberg levels with L⩾5 were measured using microwave spectroscopy, determining the relative positions of all twenty levels with sub-MHz precision. Analysis of the measured pattern using the effective potential model yields determinations of the quadrupole moment, scalar and tensor dipole polarizability, and g factor for the 2P3∕2 ground state of Ar+: Q=−0.520 83(2)ea02, αd,0=6.807(2)a03, αd,2=0.077(2)a03, gJ=1.335(17). © 2008 The American Physical Society URL:
