Изотопи на итербиумот

Природниот итербиум (70 Yb) е составен од седум стабилни изотопи: 168Yb, 170Yb &#x2013; 174 Yb и 176Yb, со 174Yb кои се најзастапени (31,83% природно изобилство). Карактеризирани се 30 радиоизотопи, од кои најстабилни се 169Yb со полураспад од 32.014 денови, 175Yb со полураспад од 4.185 денови и 166Yb со полураспад од 56,7 часа. Сите преостанати радиоактивни изотопи имаат полураспад кој е помал од 2 часа, а поголемиот дел од нив имаат полураспад помал од 20 минути. Овој елемент, исто така, има 18 мета состојби, при што најстабилна е 169mYb (t1/2 46 секунди).

Изотопите на итербиум се движат од 149Yb до 187Yb. Примарниот распаден режим пред најзастапениот стабилен изотоп, 174Yb е  преку електронски зафат, а примарниот режим после е бета-распадот. Примарните распадни производи пред 174Yb се изотопи на тулиум, а примарните производи потоа се изотопи на лутетиум. Од интерес за современата квантна оптика, различните изотопи на итербиум ја следат или статистиката на Бозе-Ајнштајн или статистиката на Ферми-Дирак, што доведува до интересно однесување во оптичките решетки.
