Isotopen van renium
Es Chemisches ElementRhenium (Re), mit a Atommasse ab 186.207(1) Sie, besitzt 1 Stall Isotop: 185Re, jetzt sofort Fülle von etwa 37,4 %. Dieses Isotop wird vermutet, dass es durch ist -zerfallen zum stabilen Isotop zerfallen 181Ta. Darüber hinaus in der Natur auch die Radioisotop187Re denn, dieser halbes Leben ab 41 MilliardeJahr und ist auch das am häufigsten vorkommende Isotop dieses Elements (ca. 62,4%). Ebenfalls Indium und Tellur dieses Phänomen zeigen. Rhenium-187 ist auch ein primordiales Radionuklid, die in der verwendet wird Rhenium-Osmium-Datierung. Die verbleibenden 32 Radioisotope sind instabil und haben relativ kurze Halbwertszeiten (die meisten weniger als ein .). zweite).
Das kurzlebige Isotop von Rhenium ist 160Re, mit einer Halbwertszeit von etwa 860 Mikrosekunden. Die langlebigste ist 187Re, mit einer Halbwertszeit von 41 Milliarden Jahren.
