  The circumstellar disk density distributions for a sample of 63 Be southern
stars from the BeSOS survey were found by modelling their H$\alpha$ emission
line profiles. These disk densities were used to compute disk masses and disk
angular momenta for the sample. Average values for the disk mass are
3.4$\times$10$^{-9}$ and 9.5$\times$10$^{-10}$ $M_{\star}$ for early (B0-B3)
and late (B4-B9) spectral types, respectively. We also find that the range of
disk angular momentum relative to the star are between 150-200 and 100-150
$J_{\star}/M_{\star}$, again for early and late-type Be stars respectively. The
distributions of the disk mass and disk angular momentum are different between
early and late-type Be stars at a 1\% level of significance. Finally, we
construct the disk mass distribution for the BeSOS sample as a function of
spectral type and compare it to the predictions of stellar evolutionary models
with rapid rotation. The observed disk masses are typically larger than the
theoretical predictions, although the observed spread in disk masses is
typically large.
