Elements 116 and 118 are Bogus?

prostoalex writes "In this era of corporate misbehavior and overstatement of results who can you trust? Scientific sources, of course. Well, turns out people at Lawrence Berkeley National Laboratory lied about their discovery of elements 116 and 118. Associated Press has the story, quoting the lab officials charging the researchers with "scientific misconduct"."

  1. element names by Jucius+Maximus · · Score: 5, Interesting

    Maybe they announced their 'discovery' because they thought they were close to really producing the element, but did not want to let some other country (probably Russia or England) discovering it first and thus getting naming rights. There have historically been fights about who discovered what element first because everyone wants to get a chance to name an element in the periodic table.

  2. Ninov also discovered 112 (Ununbium) by Pulzar · · Score: 5, Interesting

    According to this site, element 112, Ununbium, was also discovered by this guy, V. Ninov, who forged the results of the discovery of 116 and 118.

    It begs the question -- is 112 bogus as well? If not, it makes you wonder why he did this, after previously discovering a new element already. One was not enough? :)

    Man. This hit a little close to home. I was on the team that helped "discover" those elements. I want to explain a couple of items about elemental discovery and answer some questions I saw repeated many times on this thread. Superheavy elements haven't been dug out of the ground and looked at in about 60 years. They are made either by atomic explosions in salt caves (which the CTBT forbids now), or by beam on target collisions using a cyclotron. Accelerate some particles (we used Kr), slam them into a target (we used Pb) and you get a little bit of fusion, resulting in a new element with 82+36 protons: 118. Robert Smolanczuk predicted this would be a good reaction for "cold fusion" (not the kind you are thinking of), and we could expect to see ~1 to ~10 nuclei if our detector efficiencies were high enough, with about a week of beam. (That's constant beam-- I had three midnight to 8 AM shifts on this run). We used the Berkeley Gas-Filled Separator, which is basically two 30-ton magnets and some time-sensitive avalanche and PIIPS detectors. We were looking for a characteristic decay chain. We can get the material from the target area to the detector in microseconds, sweep it onto a detector surface, "listen" for a decay on the order of 10 MeV alpha, then wait for the the element-116 left afterwards to decay with another characteristic alpha energy in a characteristic time, and so on. During the week, we had no cherry responses. The data was mined and we thought we had three promising chains. I guess now they weren't so promising. Of course, I've been kept up to date on the retraction and so forth, but I just thought the data was reanalyzed and the chains were no good or outside of statistical significance. I had no idea of this possibility until reading it here. Victor's work in Germany for 110, 111, and 112 is unbesmirchable. Those elements have been confirmed (i.e., made in another lab using the same reaction). They aren't named because the German group just hasn't named them. We bothered them for years, and I'm sure they still get requests. I know they wanted to name one for the valley the lab was in: Hassium or Lassium or something. Still hasn't happened. I'm a little embarrassed. I've lost one of my best conversation pieces--and a resume entry for that matter.
