Femtosecond high-order harmonic transient absorption spectroscopy is used to resolve the complete |j,m{r_angle} quantum state distribution of Xe{sup +} produced by optical strong-field ionization of Xe atoms at 800 nm. Probing at the Xe N4/5 edge yields a population distribution {rho}j,|m| of {rho}3/2,1/2:{rho}1/2,1/2:{rho}3/2,3/2=75{+-}6 :12{+-}3 :13{+-}6%. The result is compared to a tunnel ionization calculation with the inclusion of spin-orbit coupling, revealing nonadiabatic ionization behavior. The sub-50-fs time resolution paves the way for tabletop extreme ultraviolet absorption probing of ultrafast dynamics.
