In the electron-ion collision energy range 0-70 eV resonances due to 3s-3p,3d (DeltaN = 0) and 3s-4l (DeltaN = 1) core excitation were detected. The resonant energies and strengths were obtained by fitting to the spectrum with a anisotropic electron-energy distribution and compared to the calculated ones by using a relativistic configuration interaction flaxcible atomic code (FAC) and the distorted-wave collision package AUTOSTRUCTURE. The merged-beams recombination rate coefficients are then convolved with a Maxwellian-boltzmann distribution to obtain the temperature dependent plasma recombination rate coefficient (PRRC) within the temperature range 10³-10⁸ K.
