摘要：

The specific heat of Ar monolayer film adsorbed on basal planes of graphite has been measured for film coverage ranging from 0.31 to 0.97 monolayers for 4.2 < T < 68 K. It is found that a broad specific heat peak centered around 50 K exists over most of the submonolayer coverages until reaching monolayer completion. A comparison with recent neutron scattering and LEED studies relates the anomaly to a possible higher order phase transition between 2D solid and 2D fluid. © 1979.
