Dubnium was first reported from 1968-70 by Russian scientists at the Joint Institute for Nuclear Research in Dubna, Russia. The most stable isotope of Dubnium is 268Db. The half-life of 268Db is 29 hours, and is the longest lived transactinide. The isotopes 260Db and 261Db were first synthesized by bombarding 243Am and 22Ne ions. 260Db was reported, by a team of researchers led by Albert Ghiorso at the University of California Berkeley, to decay by the means of alpha decay. 260Db was discovered by this team to only have a half-life of 1.6 seconds. The main goal of the scientists at Berkeley was to confirm the Russian’s findings. This means that they tried using more complicated and better equipment to further prove those findings. <ref> Siebot. [http://www.infosources.org/what_is/Dubnium.html Dubnium] ''Infosources''. Web.

The isotopes 260Db and 261Db were first synthesized by bombarding 243Am and 22Ne ions. It may also be produced by combining Californium 249 with Nitrogen through Nuclear Bombardment. 260Db was reported, by a team of researchers led by Albert Ghiorso at the University of California Berkeley, to decay by the means of alpha decay. 260Db was discovered by this team to only have a half-life of 1.6 seconds.
