Sažetak


Jedna od značajnih karakteristika C60 molekula je kolektivni odgovor njegovih valentnih elektrona na elektromagnetno zračenje. Ovo kolektivno ponašanje dovodi do pojave ogromne dipolne rezonance (tzv. površinski plazmon) u apsorpcionom spektru na oko 20 eV, koji su različiti autori  i teorijski analizirali. Kada je u pitanju fotoelektronska emisija, plazmonsku ekscitaciju karakteriše posebno ponašanje na pragu jonizacije.  Prikazana je nova serija fotoelektronskih spektara K-ljuske sa težištem na kvalitativnoj analizi svih jonizacija sa ekscitacijama i procesima dvostruke jonizacije. Merenja plazmonske ekscitacije S60 prate tzv. Tomas-Dirahov zakon i u velikoj su saglasnosti sa odgovarajućim ponašanjem satelitskih ekscitacija u atomima kao što je neon.
