摘要：

The wavelength of the 6f7/2 --> 3d5/2 transition in several nickel-like ions has been measured on the Livermore electron-beam ion trap with a precision as high as 27 ppm in order to assess their utility in a resonant photopumping scheme to achieve x-ray lasing below 80 angstrom. An interpolation of the results is presented, which provides an estimate of the transition energies for ions between Dy (Z = 66) and U (Z = 92). The closest line coincidence was found for the 3d-6f transition in nickel-like Hf, which differs by 1.2 m angstrom from the wavelength of the Ly-a(2) transition in hydrogenic Cl, and for the 3d-6f transition in Tl, which differs by 0.8 m angstrom from Ly-a(1) in hydrogenic Ca.
