The autoionization spectra of Yb have been observed and studied by three-step Laser excitation. Sixteen autoionization levels of Yb in the energy range from 50443 cm-1 to 57750 cm-1 have been investigated. The total angular momentums J of two autoionization levels were determined by a polarization technique.
