Abstract Na clusters containing 10 to less than 1000 metal sodium atoms and blisters containing xenon inclusions were formed in NaCl crystal specimens prepared by xenon ion implantation to single crystal NaCl with Auences more than or equal to 2 x 1016/cm2 at the energy of 36keV. Experiments indicated that on the condition of xenon ion Auences more than or equal to 1 x 1017/cm2 the xenon inside the inclusions formed in NaCl crystal specimens is in solid state and the solid state molecules NaXe are formed through the Combination of Xe with Na in Na clusters. The chemical shift of 23Na in solid state molecules NaXe relative to 23Na in single crystal NaCl was measured and is equal to -17ppm.
