Abstract

A measurement of the specific surface area of DLX6000 Microspheres using the method of vapor pressure adsorption isothermometry yields a value of 10.0 m2/g. This observation confirms the assertion of Friedman et al. that the prominent minimum in the NMR spin-lattice relaxation rate that they observed in the19F spins of this substrate occurs just at the completion of a monolayer of adsorbed3He.
