We measure the wavelengths of the Ni-like 3d{sup 9}thinsp4dthinsp{sup 1}S{sub 0}{endash}3d{sup 9}thinsp4pthinsp{sup 1}P{sub 1} x-ray laser line in several low-{ital Z} Ni-like ions ranging from Y (Z=39) to Cd (Z=48). These wavelengths are compared with optimized level calculations using a multiconfiguration Dirac-Fock code. With the help of these results, we identify this line to very high accuracy in nonlasing plasmas from As (Z=33) to Mo (Z=42). Accurate values of these wavelengths are essential for performing plasma imaging and interferometry experiments with multilayer optics that use the x-ray laser to backlight other plasmas. These results also provide important atomic data that are currently missing about the energy of the 4dthinsp{sup 1}S{sub 0} level in the NithinspI sequence. thinsp {copyright} {ital 1998} {ital The American Physical Society}
