The autoionization spectra of the 4dnp and 4dnf, J=1 series of Sr atom have been observed in the range of 59570-60300cm-1 using three-step laser excitation method. 60 lines have been obtained, most of them can be classified into six series converging to the 4d2D3/2 and 4d2D5/2 ionization thresholds, respectively. The profile of the line and configuration interaction are also discussed.
