Existence of new element confirmed

Remember the periodic table from chemistry class in school? Researchers from Lund University in Sweden have presented fresh evidence that confirms the existence of a previously unknown chemical element. The new, super-heavy element has yet to be named.

An international team of researchers, led by physicists from Lund University, have confirmed the existence of what is considered a new element with atomic number 115. The experiment was conducted at the GSI research facility in Germany. The results confirm earlier measurements performed by research groups in Russia.

"This was a very successful experiment and is one of the most important in the field in recent years", said Dirk Rudolph, Professor at the Division of Atomic Physics at Lund University.

Besides the observations of the new chemical element, the researchers have also gained access to data that gives them a deeper insight into the structure and properties of super-heavy .

By bombarding a thin film of with , the research team was able to measure photons in connection with the new element's alpha decay. Certain energies of the photons agreed with the expected energies for X-ray radiation, which is a 'fingerprint' of a given element.

The new super-heavy element has yet to be named. A committee comprising members of the international unions of pure and applied physics and chemistry will review the new findings to decide whether to recommend further experiments before the discovery of the new element is acknowledged.

The new evidence for the chemical element with atomic number 115 will be presented in the scientific journal Physical Review Letters on August 27, 2013.

Bob Lazar element! Now we can fuel our UFO's.

@bearly: Same as usual, test and improve our theories of the atomic nucleus.

"the researchers have also gained access to data that gives them a deeper insight into the structure and properties of super-heavy atomic nuclei."

So what are the properties of this element? What is its half-life?
Just want to know so we can dispel any notion of Bob-nutjob-lazar and his claim of element 115 used in UFOs. Surely this element leaves only a hint of its existence behind before rapidly decaying. Though if it lies in an island of stability...

I do find it an interesting coincidence that Germany is releasing this work, when they "supposedly" attempted to make a UFO, ie the famed NAZI BELL.

"All elements with an atomic number above 82 (lead) are unstable, and the "stability" (half-life of the longest-lived known isotope) of elements generally decreases with rising atomic numbers from the relatively stable uranium (92) upwards to the heaviest known element: 118. It increases in the range of elements 103 to 105, then decreases at element 106, and increases very slightly in the range of elements 110 to 114, hypothesized to be at the beginning of the island of stability."

"...they are expected to have radioactive decay half-lives of at least minutes or days as compared to seconds, with some optimists expecting half-lives of millions of years..."

Sometimes it's just good to know things,,,, we would still be playing with sharpened sticks if always stopped at the point where the question "What is it good for" came up.

Should be named Elerium.

I believe it is already known as Reflective Matter!!!<3

I think in consideration of Bob Lazar touting this as a known and stable element 25 years ago makes him a good candidate for the name. I propose " Lazarium"

Now we can finally bring out all of those captured disk craft/UFO's stored in area 51, fuel them up, and fly them around!
