激光感生碰撞能量转移实验

Experiments of Laser Induced Collision Energy Transfer

首次观察到Eu(6s6p) 8P9 2 至Sr(5s10s) 1 S0 、准稳态翼为紫翼的激光感生碰撞能量转移实验现象 ,其荧光波长为 45 8 42nm ,峰值转移激光波长为 45 9 75nm ,并对其激发函数谱随温度和随转移激光能量改变进行实验研究 ,测量了激光感生碰撞能量转移谱的截面 ,证实了激光感生碰撞能量转移谱为非对称谱。

Laser induced collision energy transfer (LICET) for transition from Eu (6s6p)8P9/2 to Sr(5s10s)1S0 is observed at fluorescence 458.42 nm and with the peak transfer wavelength of 459.75 nm. The quasi-static wing of LICET is observed and the dependence of the excitation function spectral on the temperature and the intensity of transfer laser is investigated. The experimental cross sections of LICEFT is measured and the asymmetrical spectral line of LICET is confirmed.
