Isotop iterbium

**[[Iterbium]]** (**<sub>70</sub>Yb**) yang terbentuk secara alami terdiri dari tujuh isotop stabil, 168Yb hingga 176Yb (kecuali 169Yb dan 175Yb), dengan 174Yb merupakan yang paling melimpah (31,83% kelimpahan alami). Dua puluh tujuh radioisotop telah dikarakterisasi, dengan yang paling stabil adalah 169Yb dengan waktu paruh 32,026 hari, 175Yb dengan waktu paruh 4,185 hari, dan 166Yb dengan waktu paruh 56,7 jam. Semua isotop radioaktif yang tersisa memiliki waktu paruh kurang dari 2 jam, dan sebagian besar memiliki waktu paruh kurang dari 20 menit. Unsur ini juga memiliki 12 keadaan meta, dengan yang paling stabil adalah 169mYb (*t*1/2 46 detik).

Isotop iterbium memiliki berat atom berkisar mulai dari 147,967&nbsp;u (148Yb) hingga 180,9562&nbsp;u (181Yb). Mode peluruhan utama sebelum isotop stabil yang paling melimpah, 174Yb adalah penangkapan elektron, dan mode utama sesudahnya adalah peluruhan beta. Produk peluruhan utama sebelum 174Yb adalah isotop tulium, dan produk utama sesudahnya adalah isotop lutesium. Menarik untuk optik kuantum modern, isotop iterbium yang berbeda mengikuti statistik Bose–Einstein atau statistik Fermi–Dirac, yang mengarah pada perilaku menarik dalam kisi optik.
