Laser optogalvanic spectroscopy of the even-parity Rydberg states of atomic mercury
- Atomic and Molecular Physics Laboratory, Quaid-i-Azam University 54320 Islamabad (Pakistan)
We present new experimental data on the highly excited levels in mercury using the optogalvanic detection technique in conjunction with a dc discharge cell. The collisionally populated 6s6p {sup 3}P{sub 2} metastable level has been used as an intermediate level to access the Rydberg states using a frequency-doubled dye laser covering the wavelength region between 370 and 249 nm. The optogalvanic data reveal 6sns {sup 3}S{sub 1}(13{<=}n{<=}50), 6snd {sup 1}D{sub 2}(6{<=}n{<=}18), 6snp {sup 3}D{sub 1}(6{<=}n{<=}14), 6snd {sup 3}D{sub 2}(6{<=}n{<=}15), and 6snd {sup 3}D{sub 3}(6{<=}n{<=}59) Rydberg series. The 6sns {sup 3}S{sub 1} and 6snd {sup 3}D{sub 3} Rydberg series to such a high n value have been reported for the first time. In addition, collisionally induced parity-forbidden transitions 6snp {sup 3}P{sub 1}(44{<=}n{<=}50) have been detected.
