The measured radiative recombination rate coefficients for electron-ion relative energies in the range 0–1000 meV demonstrate the importance of relativistic effects. The observed asymmetry of the measured K-RR x-ray emission with respect to the cooling energy, i.e., zero average relative velocity (⟨vrel⟩=0), are explained by fully relativistic RR calculations. With our new approach, we show that the study of the angular distribution of RR photons for different relative energies opens new perspectives for detailed understanding of the RR of ions with cooling electrons in cold magnetized plasma. application/pdf https://folia.unifr.ch/global/documents/304637 https://folia.unifr.ch/documents/304637/files/dou_ssx.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevA.92.032710 info:eu-repo/semantics/openAccess License undefined Physical Review A. - 2015, vol. 92, no. 3, p. 032710 info:eu-repo/classification/udc/53 Subshell-selective x-ray studies of radiative recombination of ${\mathrm{U}}^{92+}$ ions with electrons for very low relative energies http://purl.org/coar/resource_type/c_6501
