Atomic data (energy levels, radiative rates, electron collision strengths, and excitation rate coefficients) of 107 fine-structure levels of the (1s22s22p6)3s23p63d10, 3s23p63d94l, 3s23p53d104l, and 3s3p63d104l (l=s,p,d,f) configurations of nickel-like Ta ions are calculated using the distorted-wave approximation. Coupled with these atomic data, a hydrodynamic code MED103 is used to optimize the nickel-like Ta x-ray laser at 4.48 nm. Using the optimized drive-pulse configuration, an experiment is conducted to generate the nickel-like Ta x-ray laser at 4.48 nm.
