Title: Priority claims for the discovery of elements with atomic number greater than 111

Task Group
Chairman:
Paul J. Karol

Members: Robert C. Barber, Hiromichi Nakahara, Emanuele Vardaci, and Erich Vogt

Remark: Joint IUPAP/IUPAC Working Party

Objective: The IUPAC/IUPAP Joint Working Party is charged with examining the priority claims for the discovery of elements with atomic number greater than 111.

Description:
The procedures to be followed in assigning priorities and the subsequent naming process will be the same as those used for the recently named elements darmstadtium and roentgenium with atomic numbers 110 and 111, respectively.

In brief, the submissions received will be examined by a IUPAC/IUPAP Joint Working Party of experts the membership of which is approved by the Presidents of IUPAC and of the International Union of Pure and Applied Physics (IUPAP). The JWP will issue its findings in the form of a report and the successful claimants will then be invited to propose a name for any element for the discovery of which they have been given priority. The details of procedures are set out in detail in the IUPAC web:
> Naming the Elements

Progress:
Claims for the discovery of elements of atomic number greater than 111 have been invited and the scientists name below have submitted the following claims:

  • Dr. Amnon Marinov, The Hewbrew University, Jerusalem, Israel; for element 112
  • Dr. Kosuke Morita, The Institute of Physical and Chemical Research, Riken, Japan; for element 112 (in part) and element 113
  • Dr. Sergey Dimitriev, Joint Institute for Nuclear Research, Dubna, Russia; for elements 112, 113, 114, 115, 116, and 118
  • Dr. Sigurd Hofmann, Gesellschaft fur Schwerionenforschung mbH, Darmstadt, Germany; for element 112
