WebAt temperatures of about 100,000,000 to 200,000,000 K (1 to 2 × 10 8 K), three helium nuclei can fuse to form carbon. This reaction takes place in the following way: two helium nuclei combine to form an unstable isotope of beryllium , which has an extremely short life; rarely, a third helium nucleus can be added to form carbon before the beryllium decays . WebFor helium-3 to form a superfluid, it must be cooled to a temperature of 0.0025 K, or almost a thousand times lower than helium-4 (2.17 K). This difference is explained by quantum statistics , since helium-3 atoms are fermions , while helium-4 atoms are bosons , which condense to a superfluid more easily.
