The theoretical and experimental analysis of the spectra of Ni-like ions wa
s made, which made it possible to determined more correctly wavelengths of
the 4p(1)P(1)-4d(1)S(0) laser transitions in the YXII-MoXV ions and identif
y for the first time these transitions in the AsVI, BrVIII, and RbX ions. F
or the MoXV ion, the lines of the 3d(9)4p-3d(9)4d transitions were identifi
ed, and from a list of 18 levels of the 3d(9)4d configuration, the energies
of 14 levels were measured. Moreover, the strongest lines of the 3d(9)4d-3
d(9)4f transitions in the RbX-MoXV ions were identified and energies for a
number of levels of the 3d(9)4f configuration for these ions were determine
d.
