I can finally talk about 264
Sg since Gregorich's paper came out this week. The paper is cool for many reasons and not only because I'm a co-author. The paper recounts the Seaborgium-264 discovery by our group earlier this year from the nuclear reaction of 238
Sg. We observed a total of 5 events of Seaborgium. The events are summarized in the figure below.Taken from: http://dx.doi.org/10.1103/PhysRevC.74.044611
It sucks to read a table, like the one above, to try and figure out general decay properties of a nuclide. So instead of reading through all the known literature values for a nuclide, we'll condense the above information into a little box like this one I made (shown below).
The percentage of green signifies the probability it will undergo spontaneous fission. For 264
Sg it will undergo spontaneous fission 100% of the time, thus the box is completely filled green. These decay boxes are traded between nuclear chemists as kids trade with Pokemon cards. All nuclear chemists want to keep up to date on the latest decay systematics for any given nuclide, but it's a pain to always track them down and then update your existing files with new data and making sure you didn't miss any other data from the literature. So I'll most likely use this blog as one mechanism I'll incorporate to keep track of new data.
Very recently Nishio also published some of his results regarding Sg-264.Taken from: http://dx.doi.org/10.1140/epja/i2006-10091-y
Nishio calculated a half-life of 120.7 ms from 3 atoms detected. Summing Nishio's work with our experiment we can have a better value for 264
Sg true decay properties, shown below.
Enjoy the latest trading card.
