The ab initio calculations of electron-impact resonant excitation rate coefficients from the ground level to 54 fine-structure levels of 3d941(l=s,p,d,f)configurations of Ni-like tantalum ion are performed by using a fully relativistic distorted-wave approximation.The configuration-interaction effects are taken into account.The decays to autoionizing levels possibly followed by autoionization cascades are also included in the calculation.The contributions from doubly-excited intermediate states of Cu-like 3l17nl "l"(n=4,5;n"=5-15)arecalculated explicitly,and the contributions from high Rydberg states(n"＞15)are taken into account by using n-3 scaling law.The present results should be more accurate than the existent calculations.
