The wavelength of the 2{ital p}{sub 3/2}{r arrow}1{ital s}{sub 1/2} transition in hydrogenlike Ni{sup 27+} has been measured with an accuracy of 13 ppm. Bare Ni{sup 28+} ions of 11.4 MeV/amu as emerging from a carbon stripper foil were decelerated to 8.4, 6.7, 5.2, and 3.1 MeV/amu and dressed in a thin target gas by electron capture. The x rays were measured with a crystal spectrometer in Johann geometry employing a position-sensitive x-ray detector. The 1{ital s} Lamb shift in hydrogenlike nickel has been found to be 5.07{plus minus}0.10 eV in good agreement with theory.
