&lt;p&gt;&lt;b&gt;Neue Seite&lt;/b&gt;&lt;/p&gt;&lt;div&gt;'''312 Relativistischer Massenzuwachs'''&lt;br /&gt;
&lt;br /&gt;
Schnelle relativistische Elektronen aus den Beta Zerfällen des 90Sr (Strontium) und des nachfolgenden 90Y (Yttrium Eβ,max = 2,27 MeV) werden mit Hilfe eines einfachen Betaspektrometers analysiert. Dabei werden die Elektronen in ein nahezu homogenes Magnetfeld (B = 1,0 kG = 0,10 T), das zwischen einem permanent-magnetischen Plattenpaar (230 x 200 x 28) mm³ besteht, hineingeschossen und halbkreisförmig abgelenkt. Aus dem Austrittsort der Elektronen aus dem Magnetfeld lässt sich der Impuls der Elektronen ermitteln. Die zugehörige Energie der Elektronen wird mit einem CsI-Szintillationsdetektor, der vorher mit Standardpräparaten geeicht werden muss, mit Hilfe eines Vielkanalanalysators, bestehend aus ADC und PC, gemessen. Nach Korrektur der Energieverluste der Elektronen in Luft und im Al-Fenster des Szintillationsdetektors, werden die experimentell bestimmten Wertepaare Energie und Impuls graphisch mit Fehlerbalken dargestellt und im gleichen Diagramm mit den berechneten Energie-Impuls-Kurven für den nicht-relativistischen und den relativistischen Fall verglichen.&lt;br /&gt;
&lt;br /&gt;
Der Versuch findet im F-Praktikums-Raum NB 04/286 statt.&lt;br /&gt;
