应用时间分辨傅里叶变换红外光谱法观察用纳秒ArF（λ =193 nm）脉冲激光照射Au靶后产生的发射。将具有15 mJ输出能量的高重复率激光（1.0 kHz）聚焦在真空室（平均压力10{sup-2} Torr）内的旋转金属靶上。在1800- 4000 cm {sup-1}光谱区观察到红外发射光谱，其时间曲线显示在激光照射后9-11 μ s内出现最大发射强度。七个突出的线，其中大部分被确定为是由于低里德堡nl态的Au与n=5-10和l=0-3之间的转换。对2518.489cm{sup-1}线给出了另一种鉴别（6 f {sub 5/2}-> 7 d {sub 3/2}），该线以前被分类为8d{sub 5/2}-> 5 f {sub 5/2}。根据测得的谱线，报道了Au原子的三个f能级，并给出了其他六个能级的修正值。
Time-resolved Fourier-transform infrared spectroscopy was applied for observations of the emission arising after irradiation of a Au target with a pulsed nanosecond ArF (lambda=193 nm) laser. A high-repetition-rate laser (1.0 kHz) with an output energy of 15 mJ was focused on a rotating metal target inside a vacuum chamber (average pressure 10{sup -2} Torr). The infrared emission spectra were observed in the 1800-4000cm{sup -1} spectral region with a time profile showing maximum emission intensity in 9-11 mus after a laser shot. Seven prominent lines are reported; most of them are identified as being due to transitions between low Rydberg nl states of Au with n=5-10 and l=0-3. An alternative identification (6f{sub 5/2}->7d{sub 3/2}) is given for the 2518.489cm{sup -1} line previously classified as 8d{sub 5/2}->5f{sub 5/2}. On the basis of the measured lines, three f levels of the Au atom are reported and revised values are given for six other levels.
