Abstract
We have compared the stability of two distinct atomic frequency standards. One is based on an atomic cold cloud of 133Cs atoms in free expansion, interrogated by a Rabi resonance. The other standard is based on a thermal Cs beam interrogated by the separated oscillatory field method (Ramsey’s method). The atomic expanding cloud standard shows better stability and technical advances based on its simplicity.
