Q-value effects on the production of superheavy nuclei

Recent progress in theoretical nuclear physics related to large-scale scientific facilities

“…The results show that the production cross sections of superheavy nuclei do not decrease monotonously as the atomic number Z increasing. The cross sections of the superheavy nuclei at Z = 112 and 115 are enhanced as compared with the whole Z-trend in synthesis of the superheavy nuclei, which clearly illustrates that the reactions with large negative Q-value and shell correction are more favorable to synthesize superheavy nuclei [71].…”

“…The Cooling Storage Ring of Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) [8][9][10] was completed in 2007, which aims at the exploration of physics with radioactive ion beams, including the structure of unstable nuclei, isospin dependence of nuclear matter, heavy-ion fusion reactions, superheavy nuclei synthesis, hadronic physics, physics of high-energy density matter, physics of highly charged ions, and applications. Recently direct mass measurements of short-lived A = 2Z −1 nuclides 63 Ge, 65 As, 67 Se, and 71 Kr were carried out at HIRFL-CSR and these results have a great impact on nucleosynthesis in the rp process [11][12][13][14]. Shanghai Synchrotron Radiation *Corresponding author (email: egzhao@mail.itp.ac.cn) Facility (SSRF) [15], which was finished and commissioned in April 2009, and Daya Bay nuclear power complex in China [16] also provides many opportunities for nuclear science.…”

Effect of enantiomeric excess on the phase behavior of antiferroelectric liquid crystals

“…One is the method we report in this paper, by reducing EE of C10. The second one is by studying mixtures of compound showing first order and supercritical SmC * α -SmC * transition [18]. Here we argue the first method is superior, because it minimized the complications brought in through the different SmA-SmC * α transition temperatures in the mixtures with other compounds.…”

Fusion probability and survivability in estimates of heaviest nuclei production

“…Asymptotic values of P fus derived from Fermi-function fits to the 26 Mg, 30 Si + 238 U data and values corresponding to very asymmetric reactions leading to the 264 Rf * CN (see Refs in [51]) are shown by filled triangles with error bars. The P fus values obtained with the diffusion model [62] for reactions leading to the 274 Hs * CN are also shown by squares. Fig.…”
