Absolute total electron-ion recombination rate coefficients of argonlikeSc3+(3s2 3p6) ions have been measured for relative energies between electronsand ions ranging from 0 to 45 eV. This energy range comprises all dielectronicrecombination resonances attached to 3p -> 3d and 3p -> 4s excitations. A broadresonance with an experimental width of 0.89 +- 0.07 eV due to the 3p5 3d2 2Fintermediate state is found at 12.31 +- 0.03 eV with a small experimentalevidence for an asymmetric line shape. From R-Matrix and perturbativecalculations we infer that the asymmetric line shape may not only be due toquantum mechanical interference between direct and resonant recombinationchannels as predicted by Gorczyca et al. [Phys. Rev. A 56, 4742 (1997)], butmay partly also be due to the interaction with an adjacent overlapping DRresonance of the same symmetry. The overall agreement between theory andexperiment is poor. Differences between our experimental and our theoreticalresonance positions are as large as 1.4 eV. This illustrates the difficulty toaccurately describe the structure of an atomic system with an open 3d-shellwith state-of-the-art theoretical methods. Furthermore, we find that arelativistic theoretical treatment of the system under study is mandatory sincethe existence of experimentally observed strong 3p5 3d2 2D and 3p5 3d 4s 2Dresonances can only be explained when calculations beyond LS-coupling arecarried out.
