Our main goal is to analyse transformation - and interaction processes of disk galaxies within the special environment of clusters as compared to the hierarchical evolution of galaxies in the field. Spatially resolved multi object spectra have been obtained for seven galaxy clusters at 0.3<z<0.6 to measure rotation velocities of cluster members. For three of the clusters, Cl 0303+17, Cl 0413-65, and MS 1008-12, for which we presented results including a Tully-Fisher-diagram in Ziegler et al. (2003ApJ...598L..87Z), we describe here in detail the sample selection, observations, data reduction, and data analysis. Each of them was observed with two setups of the standard MOS-unit of FORS.

Note (1): Type of SED in the de Vaucouleurs scheme as follows: 1 = Hubble type Sa 3 = Hubble type Sb 5 = Hubble type Sc 8 = Hubble type Sdm Note (2): In some cases there was no [OII] line within the spectra and we used other emission lines.
Global notes: Note (G1): Galaxies are identified as [JZB2004] MS 1008-12 ANNa, [JZB2004] Cl 0303+17 ANNa and [JZB2004] Cl 0413-65 ANNa in Simbad,
