Isotopen van lutetium
Es Chemisches ElementLutetium (Lu), mit a Atommasse ab 174.967(1) Sie, besitzt 1 Stall Isotop: 175Lu, der verdächtigt wird, -zerfallen zum Radioisotop zerfallen 171tm. Das Isotop hat a natürliche Fülle von 97,41 %. Das andere natürlich vorkommende Isotop ist das Radioisotop176Lu, der halbes Leben ab 38,5 MilliardeJahr Besitz. Die verbleibenden 32 Radioisotope sind instabil und haben relativ kurze Halbwertszeiten (die meisten weniger als ein .). zweite).
Das kurzlebige Isotop von Lutetium ist 150Lu, mit einer Halbwertszeit von etwa 43 Millisekunden. Die langlebigste ist 176Lu mit einer Halbwertszeit von 37,8 Milliarden Jahren.
