摘 要: | 运用时间分辨激光诱导荧光技术和激光诱导等离子体方法测量了铂原子的15条奇宇称高激发态能级的自然辐射寿命.测量结果处于6.1到116 ns之间,且误差低于10%.经比较,与前人结果在误差范围内符合很好.据文献调研所知,结果中有5条高度接近60000 cm~(-1)的高激发态能级的寿命值是未见报道的.

Abstract: | Radiative lifetime measurements of 15 highly excited odd-parity levels of Pt I were performed using time-resolved laser-induced fluorescence (TR-LIF) technique in laser-produced plasma. The measured lifetime values range between 6.1 and 116 ns with an uncertainty of 10% or less. Comparison with previous results reveals a good agreement. To our knowledge, five of these excited levels, which approach to 60000 cm−1, were measured for the first time. |
