Abstract:

The work supported by this AFOSR grant during the past year was focused on the fundamental physics and the applications of spin polarized species. The most notable accomplishments of the past year were 1 basic work basic physics needed to transform gas-cell atomic clocks based on optically-pumped alkali-metal atoms from secondary frequency standards to primary frequency standards 2 completion of studies of optical pumping and magnetic resonances of spin-polarized metastable Xe atoms as potential candidates for atomic clocks 3 detailed studies of nuclear and electron spin currents from an optically pumped vapor to cell walls 4 initial studies of the optical pumping of alkali-metal atoms under laboratory conditions similar to those prevailing in sodium guidestars used in adaptive optics 5 Personnel supported by this AFSOR grant or its predecessors have published a book Optical Pumping of Atoms, based on work that AFOSR has supported over the years.
