1.06μm区域的Cs_2分子吸收光谱

Molecular Cesium Absorption Spectra near 1.06 μm

用ＲＫＲ（Ｒｙｄｂｅｒｇ－Ｋｌｅｉｎｎ－Ｒｅｅｓ）方法计算了Ｃｓ２分子的Ｘ１＋ｇ和Ａ１＋ｕ的势能曲线，求解了Ｃｓ２分子核运动的径向薛定谔方程，获得Ｘ态与Ａ态间跃迁的Ｆｒａｎｃｋ－Ｃｏｎｄｏｎ因子和１．０６μｍ附近区域的吸收光谱，并与实验测得的吸收光谱作了比较。

The potentials for molecular cesium (Cs 2) X 1?  + g and A 1? + u states have been calculated by RKR method. A set of Franck Condon factors for X state (v '=0￣30)A state (v ′=0￣30) have been obtained by solving radial Schrodinger equation of nuclei. The absorption spectra is demonstrated in the wavelength near 1.06 μm. The calculated absorption spectra are in good agreement with experimental ones.
