Liste der Isotope/Ordnungszahl 61 bis Ordnungszahl 70

Liste der Isotope ist die Übersichtsseite, um komfortabel auf alle Elemente zugreifen zu können. Dort wird auch der Aufbau erklärt und die Legende zur Tabelle ist auch dort zu finden. Zerfallsenergien wurden mit den angegebenen Massen und dem Masse-Energie-Äquivalent von ${\displaystyle \textstyle \Delta m=931{,}4940954{\frac {\mathrm {MeV} }{\mathrm {u} }}}$ neu berechnet.

Ein #-Zeichen hinter den Zahlenwerten bedeutet ein nicht experimental ermittelter geschätzter Wert.
