Isotopen van thulium
Es Chemisches ElementThulium (Tm), mit a Atommasse ab 168.93421(2) Sie, besitzt 1 Stall Isotop: 169Tm, der verdächtigt wird, -zerfallen zum stabilen Isotop zerfallen 165Whoa. Es ist auch das einzige natürlich vorkommende Isotop dieses Elements, was es zu einem der mononuklidische Elemente. Die 33 Radioisotope sind instabil und haben eine relativ kurze Halbwertszeit (die meisten weniger als eins). zweite).
Das kurzlebige Isotop von Thulium ist 145Tm, mit einer Halbwertszeit von etwa 3,1 Mikrosekunden. Die langlebigste ist 171Tm, mit einer Halbwertszeit von 1,92 Jahr.
