the 1930’s called atomic beam magnetic resonance. 1949 Using Rabi’s technique‚ NIST (then the National Bureau of Standards) announces the world’s first atomic clock using the ammonia molecule as the source of vibrations. 1952 NIST announces the first atomic clock using cesium atoms as the vibration source. This clock is named NBS-1. 1954 NBS-1 is moved to NIST’s new laboratories in Boulder‚ Colo. 1955 The National Physical Laboratory in England builds the first cesium-beam clock used
