In the present paper the analysis of an intermittent time series obtained from a nonlinear system is presented. The setup is driven by phase transitions and has no external periodic driving. The observed states range from stable ones over periodicity and intermittence to chaotic behavior. The data in the intermittent regime are analyzed with respect to the optical shape, the frequency distribution of the laminar lengths, and the $\gamma$ parameter. The results of these analyses are compatible with the interpretation of the presence of intermittence type II in the system under investigation. Additionaly the reconstruction of the radius dynamics of the experimental data is attempted. The corresponding results also indicate type II intermittence. Some weight is put on figuring out the principal problems, arising in the reconstruction of the Ne$\stackrel{\mathrm{̆}}{\mathrm{ı}}$mark-Sacker dynamics from a scalar time series.
