Moroshkin, Peter Lebedev, Victor Weis, Antoine 2014-06-07 We present an experimental study of the laser-induced luminescence spectra of Mn atoms in solid helium matrices. We observe transitions of the valence electron and of inner-shell electrons. We find that the Mn-He interaction perturbs the inner-shell transitions to a lesser extent than the valence-electron transitions. The observed lineshapes of the inner-shell transitions of Mn are similar to those of an inner-shell transition in Ba studied earlier. At the same time, they are more strongly perturbed than the corresponding transitions in Au and Cu under the same conditions. We suggest a qualitative explanation of these observations based on the atomic bubble model. Our results also suggest that the inner-shell transitions of Mn in solid He are more strongly perturbed than the same lines of Mn isolated in solid Ar or Kr matrices. application/pdf https://folia.unifr.ch/global/documents/303759 https://folia.unifr.ch/documents/303759/files/wei_sma.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1063/1.4880556 info:eu-repo/semantics/openAccess License undefined The Journal of Chemical Physics. - 2014, vol. 140, no. 21, p. 214314 info:eu-repo/classification/udc/53 Spectroscopy of Mn atoms isolated in solid ⁴He http://purl.org/coar/resource_type/c_6501
