Hassium, formerly known as unniloctium or eka-osmium is an artificial element; from wikipedia: <<The element was first observed in 1984. Several isotopes are known with 269Hs being the longest-lived with a half-life of ~10 s. There is also tentative evidence for an isotope 277bHs with a measured half-life of ~16.5 minutes, which would make it one of the longest-lived superheavy nuclides. More than 100 atoms of hassium have been synthesized to date in various cold and hot fusion reactions, both as a parent nucleus and decay product.>> If anybody had a pseudopotential for it, it would be by far the element with the highest ratio for the number of available pseudopotentials over the number of available atoms. Honestly, I doubt there is any serious application for it in the field of condensed matter physics. regards -- Lorenzo Paulatto *** Note: my affiliation has changed! please send future correspondence to: <Lorenzo.Paulatto at impmc.upmc.fr> *** post-doc @ IMPMC/UPMC - Universit?
