Laboratory-made fleeting element to join periodic table

india Updated: Aug 29, 2013 01:34 IST

Remember the periodic table from chemistry class in school? It may soon have a new member! Scientists have confirmed the discovery of a new super-heavy element - with atomic number 115 - and it may soon be on its way to join the periodic table.

An international team of researchers conducted an experiment 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 in Sweden.

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 atomic nuclei.

By bombarding a thin film of americium with calcium ions, 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 is 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 has been published in the journal The Physical Review Letters.
