Abstract

Abstract: We have measured the photoabsorption spectra of Pb II and Bi III in the wavelength range between 37 and 70 nm. A number of features in the spectra have been identified with the aid of the Cowan suite of atomic codes. 5d → 6p transitions from the ground configuration (5d 10 6s 2 6p) and three excited configurations (5d 10 6s 2 6d, 5d 10 6s 2 7s, 5d 10 6s6p 2 ) give rise to the most prominent features in the measured spectra. Evidence of excited states including (5d 10 6s6p 2 ( 4 P3/2, 4 D3/2 )) for Pb II and (5d 10 6s6p 2 ( 4 P1/2, 4 P3/2 )) for Bi III was observed in our measurements.
