New Isotope Discovery: Borhium-260
by mitch on Jan 15 2008 (2642 Views)The discovery of a new isotope of Bohrium, by Nelson et al. (I'm a coauthor as well), was published yesterday in PRL. In total, 8 events of 260Bh were reported. Unfortunately, the new isotope is not long-lived enough to be of practical chemical interest. A summary of the decay properties is summarized in the Nuclear Trading Card format shown below.
The yellow color signifies the observation that it decays by alpha emission 100% of the time. The nuclide decays into 256Db, which is long-lived enough for chemistry, and the results taken with this paper and others updates the known decay properties of Dubnium-256. The updated trading card is below.
In this case the red signifies an ~30% electron capture branch. I hope you enjoy the announcement of a new member to the Bohrium family, and have fun with your new nuclear trading card.
