$\begin{figure} { \psfig{file=0350f1.ps,width=10.8cm,angle=0,clip=0} }\end{figure}$ Figure 1: Evolution of the mean width of the jet/ambient mixing layer with time for all the simulations. Different types of lines are used for models with different internal energies: Continuous line: model A; dotted line: model B; dashed line: model C; dashed-dotted line: model D. Line thickness increases with Lorentz factor (from 5, thinest line, to 20 thickest one). A value of 5 $R_{\rm j}$ for the width of the mixing layer (horizontal dashed line) serves to classify the evolution of the different models.

Left column (model B05): the ambient material carves its way through the jet difficulting the advance of the jet material which is suddenly stopped. Right column (model D05): the amount of ambient matter hampering the jet material is smaller and matter from the jet at the top of the jet crests is ablated by the ambient wind.

The corresponding times are 355, 190, 370 and 765 $R_{\rm j}/c$ . In the case of models A05, B05 and B10 this distortion leads to the formation of a shock.
