Abstract: The relativistic energies and widths of hydrogen-like ions exposed to the uniform electric field are calculated. The calculations are performed for the ground and lowest excited states using the complex scaling technique in combination with a finite-basis method. The obtained results are compared with the non-relativistic values. The role of relativistic effects is investigated.<br />Comment: 21 pages, 5 figures
