SPIN RELAXATION OF ATOMIC HYDROGEN IN CAF2: EVIDENCE FOR LOCAL MODES.
Abstract
The spin-lattice relaxation time, T sub 1, of atomic hydrogen in calcium fluoride has been measured at 3 k0e and at temperatures from 2.1K to 165K. The characteristic temperature are: theta = 474K and T sub H = 850 = 60K. Similar measurements have been made on atomic deuterium centers. The relaxation data for deuterium centers can be accurately fitted by an expression in which there is an additional term due to cross relaxation. The characteristic temperatures of 850K and 640K are interpreted in terms of local modes which involve the motion of the interstitial hydrogen and deuterium atoms with respect to neighboring fluorines. The basis for this identification is discussed in terms of Feynman diagrams. (Author)
