Hoszowska, Joanna Pajek, M. 2005-05-25 K-X-ray spectra of Zr, Nb, Mo and Pd targets bombarded with 250 MeV carbon and 360 MeV oxygen ions are studied with high resolution diffraction spectrometry. Relative yields and natural widths of the K^hα_1,2 hypersatellite lines are determined and compared with those of the diagram lines. The widths of K^hα_1,2 lines are compared with the new phenomenological formula which takes into account the retardation of the K^hα₁ transition in the LS coupling scheme. The data significantly exceed the expected values. Deduced lifetimes of the double K-hole states are shorter than expected. application/pdf https://folia.unifr.ch/global/documents/299905 https://folia.unifr.ch/documents/299905/files/1_dousse_nvh.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.nimb.2005.03.155 info:eu-repo/semantics/openAccess License undefined Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. - 2005, vol. 235 (1-4), p. 110-115 K-X-ray hypersatellites line shapes and linewidths relative intensities MCDF calculations info:eu-repo/classification/udc/53 Natural widths of hypersatellite K-X-ray lines and lifetimes of double K-hole states in mid-Z atoms http://purl.org/coar/resource_type/c_6501
