“…Decay chains of some isotopes were proposed as well [5]. A new isotope of 235 Am and the isotopes of the elements 105 and 107 with the mass weight 259 and 265, respectively, were synthesized for the first time [6]. The existence of 259 Db has been confirmed by Lawrence Berkeley National Laboratory.…”

Actinides / Nuclear energy chemistry / Radioanalytical chemistry / Radiopharmaceutical chemistry / Education and training / ChinaSummary. Nuclear and radiochemistry is one of the frontier areas of chemistry with high impact on national security, energy supply, scientific advances, social and economic development. Nuclear and radiochemistry in China is now experiencing a renaissance, which is being strongly motivated by China's huge demand for nuclear energy. With this in review, the progress in nuclear and radiochemistry of China is selectively addressed. Some hot topics have been summarized and the main research results achieved by Chinese scientists in this field are highlighted, with emphasis on the basic nuclear chemistry, actinide and trans-actinide chemistry, chemistry of spent nuclear fuel reprocessing, radioanalytical chemistry, environmental radiochemistry and radiopharmaceutical chemistry, etc. Some measures about how to promote the radiochemical education and research in China are suggested, and future perspectives are briefly outlined as well.

“…Recently, the superheavy elements Z=113-116, 118 were synthesized at FLNR in Dubna (Russia) with the double magic nucleus 48 Ca bombarding actinide nuclei [6,7,8]. New heavy isotopes 259 Db and 265 Bh have also been synthesized at HIRFL in Lanzhou (China) [9]. Further experimental works are necessary in order to testify the new synthesized SHN.…”

Within the framework of a dinuclear system (DNS) model, the evaporation-residue excitation functions and the quasi-fission mass yields in the $^{48}$Ca induced fusion reactions are investigated systematically and compared with available experimental data. Maximal production cross sections of superheavy nuclei based on stable actinide targets are obtained. Isotopic trends in the production of the superheavy elements Z=110, 112-118 based on the actinide isotopic targets are analyzed systematically. Optimal evaporation channels and combinations as well as the corresponding excitation energies are proposed. The possible factors that influencing the isotopic dependence of the production cross sections are analyzed. The formation of the superheavy nuclei based on the isotopes U with different projectiles are also investigated and calculated.Comment: 26 pages, 15 figure

“…Many isotopes of SHE with Z = 103 to 118 have been produced by heavy-ion fusion reactions in experiments [51][52][53][54] and the elements with Z up to 112 have been named. In the heavy ion research facility at Lanzhou (HIRFL) China, two new super-heavy nuclides, 259 Db and 265 Bh, were also produced [55,56] and an experiment was carried out recently which aims at repeating the synthesis of 271 Ds [57]. The production cross section and the corresponding life time of SHE decrease rapidly as the charge number Z increases.…”
