1898—1988

Rabi, N. F. Ramsey, and Zacharias applied the method to molecular hydrogen and discovered a multiplicity of reso-nance lines, whose separation arose from the magnetic in-teractions of the nuclear moments with each other and with the magnetic field caused by the rotation of the mol-ecule. They found that the separations of the resonances

methods developed later, such as nuclear magnetic resonance (NMR), electron-spin resonance (ESR) and optical pumping. In Rabi's method a beam of atoms passes through an oscillating field, and if the frequency of that field is right, transition between atomic levels can take place. In 1949 one of this year's laureates, Norman Ramsey, modified

The Nobel Prize in Physics 1989 was divided, one half awarded to Norman F. Ramsey "for the invention of the separated oscillatory fields method and its use in the hydrogen maser and other atomic clocks", the other half jointly to Hans G. Dehmelt and Wolfgang Paul "for the development of the ion trap technique".


magnetic field independent to the first approximation. However, it has also been found possible to operate the maser between the [F= 1, m= 1] and [F= 0, m= 0] levels. Such operation provides a means of measuring the average strength of the magnetic field inside the cavity.


May 18, 2018· In Ramsey's molecular beam experiments, the time spent in the resonance region was determined by the spatial separation of the first and second oscillating fields. Ramsey's desire to increase still further this time factor and thereby to increase the precision of his magnetic resonance measurements led to the invention of the hydrogen maser in ...
