WebSep 3, 2024 · The traditional Rubidium isotope of choice for atomic clocks is Rubidium-87, although I have found papers describing clocks built around Rubidium-85. I cannot readily find any references for why 87 is preferred in clocks. Rubidium-85 is the naturally more common isotope (72% vs 28% for Rubidium-87) and is radioactively stable.
