Isotopen van terbium
Es Chemisches ElementTerbium (Tb), mit a Atommasse ab 158.92535(2) Sie, besitzt 1 Stall Isotop: 159Tb, das theoretisch in der Lage ist spontane Spaltung zu durchlaufen. Es ist auch das einzige natürlich vorkommende Isotop dieses Elements, was es zu einem der mononuklidische Elemente. die 35 Radioisotope sind instabil und haben eine relativ kurze Halbwertszeit (meistens weniger als eins). zweite).
Das kurzlebige Isotop von Terbium ist 135Tb, mit einer Halbwertszeit von etwa 0,94 Millisekunden. Die langlebigste ist 158Tb, mit einer Halbwertszeit von 180 Jahr.
