    • note
    • We note that at low coverages within the Langmuir gas model, the power-law decay of φ(t) is not pronounced due to the weakness of memory effects in this case. For the same reason for any system at a low coverage. we expect a relatively narrow time window in which φ(t) decays like a power-law. Studies of φ(t) at low θ are obviously rendered by this problem.
