| May 30 The International Union of Pure and Applied Chemistry (IUPAC) officially announced: Element 114 is Named Flerovium and Element 116 is Named Livermorium. See updated Periodic Table. The synthesis of those superheavy elements was carried out by international collaboration Dubna-Livermore. who contributed to these outstanding results! No doubts, this success, related to the discovery of nuclear shell Z=114 and N=184 was strongly based on discovery of nuclear shell Z=108 and N=162 made in 90-th in experiments conducted under Yu. Lazarev leadership. Thus the official recognition of superheavy elements 114 and 116 discovery we also could consider as a gift to Yu. Lazarev 66th birthday anniversary. Now in Periodic Table we see two Dubna related elements: 105-th, which Yu.Lazarev discovered with colleagues, and 114-th, the road to which he paved out. Let me remind you, that in the title of the last Yu. Lazarev article stated: "Discovery of the Shell Closures N=162 and Z=108". And final words of the abstract were: "The findings of the present series of experiments create novel opportunities for extending the nuclear domain at its upper edge and offer the predicted spherical shells at N≃178-184 and Z=114 to be a major challenge for future experimental explorations.". |
