利用无多普勒双光子光谱和热离子二极管中的离子探测技术，测量了Cs的8s态的超精细分裂和绝对项能量。结果表明，磁偶极子耦合常数a=219.3(2)MHz，C.G.相对于C.G.的8S状态。对于基态，与较早的、不太精确的测量很好地吻合。超精细耦合也与最近的相对论Hartree-Fock计算很好地吻合。
Doppler-free two-photon spectroscopy and ion detection in a thermionic diode were used to measure the hyperfine splitting and absolute term energy of the 8S state of Cs. The results,a=219.3(2) MHz for the magnetic dipole coupling constant, andE(8S)=24317.1499(4) cm-1for the term value of the c.g. of the 8S state relative to the c.g. of the ground state, agree well with earlier, less precise measurements. The hyperfine coupling also agrees well with a recent relativistic Hartree-Fock calculation.
