ESR and x-ray investigations of deuterium atoms and molecules in impurity-helium solids Academic Article uri icon

abstract

  • Impurity-helium solids created by injecting deuterium atoms and molecules into superfluid4He have been studied via electron spin resonance (ESR) and x-ray diffraction methods. We measured the g-factor, the hyperfine constant and the spin-lattice relaxation time of D atoms in D-D2-He solids. These measurements show that D atoms are mainly stabilized in D2clusters. Using an x-ray method we found the size of D2clusters to be 90 in diameter and the densities of D2molecules in the samples to be of order 2.5 1021cm-3. The highest average concentration of D atoms achieved in D-D2-He solids was 1.5 1018cm-3. The local concentrations of D atoms within D2clusters is found to be large ( 2 1019cm-3). 2004 Plenum Publishing Corporation.
