MICROWAVE SPECTROSCOPY OF THE HIGH-L H-2 RYDBERG STATES (NU=0,R=1) N=10 G, H, I, AND K

Ten fine-structure intervals separating n = 10, L = 4,5,6, and 7 Rydberg states of H-2, all with (nu = 0, R = 1) H-2+ cores, have been measured using fast-beam microwave-optical techniques, determining the relative positions of all these states to a precision of about +/- 0.3 MHz. These experimental results are compared with predictions of the expected structure, which use the polarization model to relate the Rydberg fine structure to properties of the H-2+ ion, yielding experimental determinations of certain electric properties of the (0,1) state of H-2+: quadrupole moment, Q = 1.642 95(30)ea0(2), and dipole polarizabilities, alpha-s = 3.1770(34)a0(3), alpha-T = 4.015(36)a0(3).
