Tämä pro gradu-tutkielma koostuu kahdesta osasta. Ensimmäisessä osassa stabiilin ytterbiumin magneettinen oktupolimomentti määritetään kollineaarista laserspektroskopiaa (CLS) ja nopeaa atomisuihkua käyttäen. Mittaus suoritetaan IGISOL-laitteistolla (Ion-Guide Isotope Separator On-Line) Jyväskylän Yliopiston kiihdytinlaboratoriossa. 173-Yb:n metastabiilin tilan ylihienokertoimet mitataan käyttäen kolmea erilaista optista dipolisiirtymää. Mitatusta ylihienospektristä määritetään dipoli-, kvadrupoli ja oktupolikertoimet joista saadaan vastaavat ytimen momentit ydinteorian avulla. Tutkielman toinen osa tehdään CERN:issä ISOLDE:lla (Isotope Separator On-Line DEvice), jossa kehitetään moniheijastavan lentoaikamassaspektrometrin (MR-ToF) ja CLS...
