The superheavy nucleus 2.0Hs is expected to be a “double-magic” deformed nucleus. We have calculated its cross sections of evaporation residue for the reactions 2.8Cm(2.Mg,4n)2.0Hs, 2.4Pu(30Si,4n)2.0Hs, 2.8U(36S,4n)2.0Hs and 2.6Ra(48Ca,4n)2.0Hs using a two-parameter Smoluchowski equation. It is found from our results that 2.6Ra(48Ca,4n)2.0Hs and 2.8U(36S,4n)2.0Hs are two optimal reactions for the synthesis of the superheavy nucleus 2.0Hs due to their large negative Q-values.

The production of superheavy nuclei with Z=108-116 via hot fusion reactions of the neutron-rich projectiles with 2.8U target is systematically *** results show that the production cross sections of superheavy nuclei do not decrease monotonously as the atomic number Z *** 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.

Direct imaging and determination of the crystal structure of six-layered graphdiyne

Nano Research 2018年第3期11卷 1714-1721页

Since its discovery, the direct imaging and determination of the crystal structure of few-layer graphdiyne has proven difficult because it is too delicate under irradiation by an electron beam. In this work, the crystal structure of a six-layered graphdiyne nanosheet was directly observed by low-voltage transmission electron microscopy （TEM） using low current density. The combined use of high-resolution TEM （HRTEM） simulation, electron energy-loss spectroscopy, and electron diffraction revealed that the as-synthesized nanosheet was crystalline graphdiyne with a thickness of 2.19 nm （corresponding to a thickness of six layers） and showed ABC stacking. Thus, this work provides direct evidence for the existence and crystal structure of few-layer graphdiyne, which is a new type of two-dimensional carbon material complementary to graphene.

由于成像板(imaging plate,IP)对电磁辐射场不敏感,因而作为探测介质被广泛应用于激光驱动的辐射粒子诊断设备中,在使用前需要对其特性和物理机制进行研究.利用^(90)Sr/^(90)Y电子源测量BAS-SR和BAS-TR两种IP板的时间衰减曲线,同时对长时间辐照的衰减曲线进行修正;刻度了BAS-SR和BAS-TR两种IP板对^(90)Sr/^(90)Y电子源的绝对灵敏度,其分别为(0.033±0.002.PSL/e和(0.0180±0.0038)PSL/e(photostimulated light,PSL),与国际上大部分电子绝对刻度的结果基本相符,IP板对辐射粒子的绝对刻度依赖于IP板的类型、扫描设备和实验环境.此外对BAS-SR和BAS-TR两种IP板辐照后进行多次连续扫描,研究了信号强度变化趋势的规律.建立了用于描述辐射粒子在IP板荧光层中沉积能量、存储信息和信息读取微观物理过程的光激励发光模型,结合光激励发光模型建立的数学模型有效地阐释了IP板探测辐射粒子物理机制与其表现的特性之间的关系.这些研究可以为后续开展IP板应用于激光等离子体诊断实验提供一定的数据基础.
