The ORNL Inventory of Isotopically Pure Actinide Targets for Super Heavy Element Synthesis.

I stumbled across this one while wandering around in the literature:

J.B. Roberto, C.W. Alexander, R.A. Boll, J.D. Burns, J.G. Ezold, L.K. Felker, S.L. Hogle, K.P. Rykaczewski, Actinide targets for the synthesis of super-heavy elements, Nuclear Physics A, Volume 944, 2015, Pages 99-116

These are the targets utilized to synthesize the super heavy elements, one of which is the halogen Tennessine, element 117. The inventory of targets is at ORNL, a very cool place if you've ever been there.

The inventory of the targets:



There's some cool descriptions of how to make these elements in the paper.

Interesting I think.
