Eine Waage für exotische Kerne: Massenbestimmung von Atomkernen mit Isoltrap

Alban Kellerbauer Frank Herfurth Klaus Blaum

subject

description

Die prazise Massenbestimmung von Atomkernen ist fur verschiedene Gebiete der Physik interessant. Penning-Fallen-Massenspektrometer wie Isoltrap am CERN konnen auch kurzlebige exotische Kerne “wiegen”, die zuvor im Labor erzeugt wurden. Die genaue Kenntnis ihrer Masse ist ein Schlussel zum Verstandnis dafur, wie Sterne, Novae und Supernovae Elemente erbruten, die schwerer als Helium sind. Isoltrap ermoglicht auch einen Test des Standardmodells: Die prazise Bestimmung von Kernmassen vor und nach einem radioaktiven Zerfall liefert wichtige Informationen uber die Natur der elektroschwachen Wechselwirkung.
