Borhium |
- Atomic Number: 107
Atomic Symbol: Bh
Atomic Weight: (262)
History:
In 1976 Soviet
scientists at Dubna announced they had
synthesized Borhium by bombarding 204Bi with
heavy nuclei of 54Cr. It is reported that earlier
experiments in 1975 had allowed scientists
"to glimpse" the new element for 2/1000
s. A rapidly rotating cylinder, coated with a
thin layer of bismuth metal, was used as a
target. This was bombarded by a stream of 54Cr
ions fired tangentially. The existence of Borhium
was confirmed by a team of West German physicists
at the Heavy Ion Research Laboratory at
Darmstadt, who created and identified six nuclei
of Borhium.
