Argon films physisorbed on a graphite substrate were studied at coverages near monolayer completion using high-resolution vapor-pressure isotherms. New experimental evidence is presented that is consistent with a picture of monolayer argon melting via a two-stage process involving the existence of an intermediate phase with short-range spatial order and solidlike properties. These findings resolve the interpretational inconsistensies concerning the melting of argon films which presently exist between the earlier thermodynamic studies and various microscopic scattering measurements.
