Comparison between the experimental and predicted values of the coefficient $\beta$ for different particle sizes $R_0$

$R_0$ ($\mathrm{\mu }$m)	${\beta }^{\exp }\hspace{0.17em}\left(\mathrm{\mu }{\text{m}}^2\right)$ [Exp.]	${\beta }^{th}\hspace{0.17em}\left(\mathrm{\mu }{\text{m}}^2\right)$ [Model]
20	0.17 $\pm$ 0.04	0.22 [0.06; 0.88]
40	1.07 $\pm$ 0.13	0.8 [0.19; 2.74]
70	8.2 $\pm$ 1.2	1.96 [0.54; 7.74]

For the model, numbers given in the brackets correspond to the boundary values of $\beta$ when the length of the fiber $L$ is decreased or increased by 5% and when $E$ and $\eta$ are varied within their experimental errors. Exp., experiment.
