Seaborgium Production

Seaborgium was obtained artificially by nuclear synthesis reaction. The great number of nucleons makes the nucleus instable, as a result of which a fission reaction may be initiated immediately after synthesizing. Seaborgium isotopes with mass numbers 259, 261, 263, 265 and 266 with different half-lives have been obtained. The ²⁶⁵Sg isotope has the biggest half-life equal to 21 s.

The first samples of Seaborgium had been synthesized via fusion of Californium-249 with Oxygen-18:

²⁴⁹₉₈Cf + ¹⁸₈O -> ²⁶³₁₀₆Sg + 4¹n

In Switzerland, at the Paul Scherrer Institute, the Seaborgium was synthesized by bombarding of Californium-248 by Neon:

²⁴⁸₉₈Cf + ²²₁₀Ne -> ²⁶⁶₁₀₆Sg + 4¹n
