查询词典 photon

To conduct such research a new experimental apparatus was established.With this setup the two-photon excitation spectra of Barium and one-photonexcitation spectra of Strontium Rydberg atoms were recorded and identified.The Stark spectra of Strontium atoms showed the "l-mixing" and "n-mixing"features. By changing laser wavelength and external electric field strengthsimultaneously, the scaled-energy spectra of Strontium 〓 Rydberg atomsat constant scaled-energy ε=-3.00,-2.50 and -1.88 were recorded for thefirst time. The experimental spectra were Fourier transformed and yielded therecurrence spectra.
