Abstract
Dielectronic-recombination (DR) rate coefficients for the ground state of Ni-like Ta45+ have been calculated for the electron temperatures in the range 0.02Ts, 3p, and 3d excitations. The rate coefficients are found to peak at very low temperature (∼80 eV) with a value of 3.58×1010 cm3/sec and reduce to 1.48×1010 cm3/sec at T=1 keV.
