Abstract For diffusion limited cluster agglomerates the ratio of the mobility radius to the radius of gyration Rm/Rg vs. N and the ratio of the mobility radius to the radius of primary particle Rm/a are determined over a range of Knudsen numbers extending into the transition region where there is a lack of data. It was found that in the large N slip regime (100 < N < 400), datapoints are found to be between the two asymptotic lines for the continuum and free molecular regimes as those datapoints are plotted in both Rm/Rg vs. N and Rm/a vs. N.
