Ununtrium Production

At the beginning Ununtrium was produced via decay of element 115, Ununpentium.

²⁸⁷₁₁₅Uup -> ²⁸³₁₁₃Uut + ⁴₂He

²⁸⁸₁₁₅Uup -> ²⁸⁴₁₁₃Uut + ⁴₂He

Japanese scientist synthesize Ununtrium by bombardment of a Bismuth-209 target by a beam of Zinc-70 nuclei accelerated to the 10% of the speed of light by RIKEN heavy ion linear accelerator. The total time of bombardment was about 1920 hours.
