      abstract     = {The wide broadening of Lyman and Balmer lines in H or H
                      mixed plasmas is a widelyobserved and studied phenomena in
                      many kinds of different plasmas, ranging fromstellar to
                      laboratory plasmas. The source of the fast H atoms in front
                      of the surface aswell as the origin of the observed emission
                      in laboratory plasmas is under controversialdiscussion. A.
                      V. Phelps proposes a "sheath-collision" model in which
                      H$^{+}$, H$^{+}_{2}$ and H$^{+}_{3}$ ions are accelerated in
                      the sheath and create fast H atoms by charge transferor
                      dissociation interaction with gas or the metallic surface.
                      There are a number ofexperiments trying to explain the
                      broadening of the lines, but the community couldonly agree
                      on the fact that the broadening is caused by the Doppler
                      effect. Usually experiments in this field are performed in
                      high pressure plasmas (p $\geq$ 1 Pa), but this makes it
                      very difficult to analyze the Doppler-shifted emission due
                      to the following reasons. On the one hand, the high pressure
                      leads to emission of accelerated ions and backscattered
                      atoms which makes the detected signal a superposition of
                      both effects. On the other hand, the emission of ions inside
                      the Debye sheath leads to a Stark broadening of the emitted
                      lines and makes the analysis of the emission spectra
                      complicated. [...]},
