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 P 3/2, 4 D 3/2 )) for Pb II and (5d 10 6s6p 2 ( 4 P 1/2 , 4 P 3/2 )) for Bi III was observed in our measurements.

Pb II和Bi III的5d→6p EUV光吸收光谱：激发态的证据

我们已经测量了Pb II和Bi III在37至70 nm波长范围内的光吸收光谱。借助Cowan原子密码套件已识别出光谱中的许多特征。从地面配置（5d 10 6s 2 6p）的5d→6p过渡和三种激发配置（5d 10 6s 2 6d，5d 10 6s 2 7s，5d 10 6s6p 2）引起了测量光谱中最突出的特征。激发态的证据包括Pb II的（5d 10 6s6p 2（4 P 3/2，4 D 3/2））和Bi III的（5d 10 6s6p 2（4 P 1/2，4 P 3/2））在我们的测量中被观察到。
