Abstract:

The major thrust of the work supported by this grant during the past year has been studies of spin polarized noble gases. The aim of the work has been to understand the gas-phase spin transfer, which in heavy noble gases is dominated by interactions in van der Waals molecules. We have measured the three body formation rates and the collisional breakup rates of these molecules. We have also measured the strengths of the major spin interactions in the molecules. We have developed a simple theory of the spin rotation interaction in alkali-noble-gas molecules. This is the first theory which successfully accounts for the observed spin rotation constants in heavy noble gases. While much of the work is basic physics there are also close ties between this work and various practical problems. Atomic frequency standards and nmr gyroscopes, are examples of applied areas which are closely related to this work.
