摘要: We present experimentally measured absolute values of the photoionization cross sections from 5s5p 1P1 and 3P1 excited states strontium at first ionization threshold as 11.4±1.8 Mb 10.7±1.7 respectively using saturated absorption technique along with a thermionic diode ion detector in conjunction Nd:YAG pumped dye laser system. These have been utilized to determine oscillator strengths 1P1↦5snd 1D2 3P1↦5snd 3D2 Rydberg transitions. The strength densities continuum corresponding state also determined by measuring five ionizing wavelengths above threshold. Smooth merging discrete f-values into has observed for series across
