Moroshkin, Peter Hofer, Adrian Nettels, Daniel Ulzega, Simone Weis, Antoine 2006 We present a theoretical and experimental study of the laser-induced formation process and of the emission spectra of Cs^*He_<i>n</i> exciplexes in the hcp and bcc phases of solid helium. Two different exciplex molecules are detected: a linear triatomic Cs^*He₂, which can exist in two electronic states: <i>A</i>π_1/2 and <i>B</i>π_3/2, and a larger complex, where six or seven He atoms form a ring around a single cesium atom in the 6<i>P</i>_1/2 state. A theoretical model is presented, which allows the interpretation of the experimentally observed spectra. application/pdf https://folia.unifr.ch/global/documents/299946 https://folia.unifr.ch/documents/299946/files/moroshkin_ces.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1063/1.2141952 info:eu-repo/semantics/openAccess License undefined Journal of Chemical Physics. - 2006, vol. 124, p. 024511 info:eu-repo/classification/udc/53 Cs^*He_<i>n</i> exciplexes in solid ⁴He http://purl.org/coar/resource_type/c_6501
