ABSTRACT

We measured electron spin echoes from deuterium atoms within deuterium-helium solids with an X-band pulse ESR spectrometer. Our two-pulse electron spin echo envelope modulation (ESEEM) measurements are well described by a model that places 50% – 60% of the deuterium atoms at the interface between the molecular deuterium nanoclusters and the superfluid liquid helium. The remainder of the atoms lie in substitutional sites within the nanoclusters. We also report the spin-lattice relaxation times T1 for these atoms. © 2006 American Institute of Physics
