我们建立了一套电热高温扩散束装置，并利用ＲＥＭＰＩ－ＴＯＦ方法获得了ＢａＦ分子ｕ＝１，１３．６≤ｎ＊≤５６各里德堡态能级结构。初步分析显示，ｎ＊＜２２各态能级结构仍具有ｓ－ｐ－ｄ－ｆｓｕｐｅｒｃｏｍｐｌｅｘ特征。
We have established a set of electric high-temperature diffusive beam devices and obtained the Rydberg states energy level structure of the BaF molecule u = 1, 13.6≤n * ≤56 using the REMPI-TOF method. Preliminary analysis shows that the n * <22 state energy level structure still has s-p-d-fsupercomplex features.
