Abstract
We measured 16 adsorption isotherms by the standard volumetric method in the temperature interval of 54–89 K and found evidence of melting for temperatures above 63 K. We assumed it to be a continuous transition, but we also discuss the possibility that it could be a first-order transition; phase diagrams are given for both assumptions. The isosteric heat of adsorption as a function of coverage is determined and our results are compared with previous work.
