| Abstract: | Laser induced collision energy transfer (LICET) for transition from Eu (6s6p) 8P 9/2 to Sr (5s10s) 1S 0 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 LICEF is measured and the asymmetrical spectral line of LICET is confirmed. |
