    "abstract": "Luminescence of surface and free bulk excitons is detected in xenon for the\nfirst time for substrate-free rare-gas clusters. Xenon clusters were produced\nby the method of gas condensation in a supersonic jet emitted into vacuum.\nOptical study was accompanied by electron diffraction measurements to determine\nthe structure of clusters.",
