Resonant soft x-ray scattering with photon energies near the OK and the Cu L₃ edges was used to study the charge ordering in the system La _1.8-x Eu_0.2 Sr_x CuO₄ as a function of temperature for x=_0.125 and 0.15. From the superstructure diffraction intensities, a charge ordering with a doping-dependent wave vector is derived which is in this system well below the transition temperature of the low-temperature tetragonal phase but well above the onset of spin ordering. This indicates that structural changes and magnetic interactions are not in general the driving force for the formation of stripelike phases in two-dimensional- doped cuprates. Analysis of the lineshape of the scattered intensity as a function of photon energy yields evidence for a high hole concentration in the stripes.
