Question

Which atoms are used in Bose - Einstein Condensate .​

Answer 1

Answer:

Bose-Einstein condensate (BEC), a state of matter in which separate atoms or subatomic particles, cooled to near absolute zero (0 K, − 273.15 °C, or − 459.67 °F; K = kelvin), coalesce into a single quantum mechanical entity—that is, one that can be described by a wave function—on a near-macroscopic scale.

To create a BEC, physicists have to cool a diffuse gas of atoms—rubidium, in that first successful experiment—to within a few millionths of a Kelvin above absolute zero.
