(135) Cs (T ½ (1/2) = 2.3 × 10 -6 a) is an interesting nuclide in many research fields, especially in environmental study. Preliminary measurements of Cs with accelerator mass spectrometry been developed with the HI-13 tandem AMS facility at China Institute of Atomic Energy (CIAE). For the purpose of suppressing ~ (135) Ba interference, experiments were carried out on differ-
