| Abstract: | This paper describes the investigation of autoionizing states near the first ionization limit of rare-earth element Dy. The 62, 51, 97 and 25 new autoionizing states resulting from the states of 4f10(5I8)6s6p(3P02)3I07, 4f9 (6H0)5d2(3F)(8G0)6s9G07, 4f9(6F0)5d6s2 7H07 and 4f95d6s2 7K07, respectively, were found by using a laser resonance ionization time-of-flight mass spectrometer (LRI-TOFMS), The photoionization efficiencies for different channels were compared with each other. In addition, the Shore-Fano parameters of autoionizing states were determined by a nonlinear fitting program. |
