Experimental History of Physics and Seaborg's Plutonium Sample

If you thought the history of physics was all about researching old papers and didn't involve lab work, a team at UC Berkeley begs to differ.  They recently published a paper describing their use of  passive radiation detection to identify what appears to be the first sample of plutonium large enough to be weighed.   The sample was made by Glenn Seaborg and his collaborators using large cyclotrons to bombard uranium with neutrons to transmute it into plutonium.  You can find the article at:
