The x-ray spectra in the range 5–8 Å emitted from laser-produced plasmas of Hf, Ta, W, and Re were observed. Lines belonging to the 3d10 - 3d9 4f and 3d10 - 3d9 4p transitions, as well as the 3p63d10 - 3p53d10 4s and 3p63d10 - 3p53d10 4d transitions in the Ni-like isoelectronic sequence, were identified. In addition, the interpretation of some previously measured lines of the same sequence were revised.
