We have used a graphite fiber as a substrate to study the kinetics of desorption and sticking of ⁴He for temperatures between 15 and 1.6 K. The sticking coefficient on the clean surface is 0.026, and is independent of coverage from 0 to 1 layer. A simple phenomenological model is used to show that the desorption rates and sticking coefficient we observe are consistent with previous thermodynamic measurements.
