摘　　要：用激光三步共振激发研究Yb原子的自电离谱,测得能量在50443一57750cm^(-1)范围内的16个自电离能级。并用偏振光技术测定两个自电离态的J值。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.
