Abstract :
This work aims at evaluating the potential of anti-spin-relaxation wall-coated cells for the development of an atomic clock based on coherent population trapping effect. We measure stability of 3·10-12 at 1 s and of about 1·10-11 at 104 s. These values seem limited by the detection noise level and the frequency drift induced by the coating, respectively.
