腐殖酸对小麦叶片衰老的影响

以叶绿素含量为指标，测定了不同浓度的腐殖酸对离体小麦叶片衰老的影响，结果表明，腐殖酸在400－900mg／L浓度范围内均有延缓衰老的作用，其中以700mg／L的腐殖酸效果最明显。     

近垒重离子熔合反应中的中子转移效应(英文)

近势垒及其以下能区重离子熔合反应中的中子转移耦合道效应是一个复杂且有争议的问题。简要介绍了近年来在中国原子能科学研究院的HI-13串列加速器上,基于静电偏转板装置完成的32S+90,94,96Zr,18O+74Ge和18O+58Ni等几个典型体系的熔合反应研究情况,并结合耦合道理论对实验数据进行了分析。选取反应体系时同时关注了正Q值的中子拾取和削裂道。另外,基于完全耦合道理论计算,提出了一种能够定量提取熔合反应中中子转移效应的自洽方法。这些研究进一步证实了垒下重离子熔合反应中的中子转移效应,同时指出了其复杂性。需要进一步的实验和理论研究来澄清相关核反应机制。The effect of neutron transfers on near-and sub-Coulomb-barrier fusion of heavy-ions is still a complicated and controversial problem. This paper reviews the recent experimental results of the fusion excitation functions of several typical systems, which have been measured by using an electrostatic deflector setup at the HI-13 tandem accelerator of CIAE. Both the neutron pickup and stripping effects were studied. Moreover, a self-consistent method to reliably isolate the transfer effect quantitatively based on the coupledchannels calculation is proposed. These studies give a further support for the neutron transfer effect on sub-barrier fusion of heavy-ions and its complexity. Further experimental and theoretical studies are needed for clarifying the relevant reaction mechanisms.     

Proton and Two-proton Emissions from Proton-rich Nuclei with 10≦Z≦20

Proton (p) and two-proton (2p) emissions from the proton-rich nuclei with 10≦Z≦20 have been explored by the in-fight decay and implantation decay methods, respectively, in a series of experiments at the HIRFL-RIBLL facility. The in-flight 2p emissions from the excited states of 28,29S /26,27P and 17;18Ne were studied by complete-kinematics measurements. Mechanisms of 2p decay and related p-p correlations have been explored. Obvious 2p correlated emissions have been observed in the cases of 28,29S but not in 27,28P, indicating the 2p halo plays an important role in the diproton emission. In the 17;18Ne cases, a small 2p opening angles were deduced by the HBT analyses, implying the BCS-BEC crossover may occur in the dilute nuclear matter. Moreover, 27S/26P/25Si, 22Si/20Mg, 23Si/22Al/21Mg, 24Si/23Al, and 36;37Ca were implanted in a thin double-sided-silicon-strip detector and their -delayed p and 2p decays have been measured by a surrounding silicon detector array under the continuous-beam mode. Important information on the nuclear spectroscopy, such as energy, lifetime, branching-ratio, and so on, has been extracted, which helps us to understand the nuclear structures of proton-rich exotic nuclei close to the drip-line.     

7Li+11B 体系唯象光学势的研究

实验测量了7Li+11B 体系的弹性散射角分布,其中弹核7Li 的入射能量分别为9.85,13.3,18.3,23.3 和28.3 MeV,测量的角度范围为θc:m: ≈ 15◦ ∼ 80◦。通过对本次实验数据以及文献中34 MeV 的数据拟合,抽取了该体系的唯象光学势参数。结果表明,在固定作用势形状因子下,势深度与能量具有线性相依的关系:实部深度随着弹核能量的增加而线性减小,而虚部深度则在平均值10.35 MeV 附近变化。Angular distributions of 7Li+11B elastic scattering were measured at Elab(7Li)=9.85, 13.3, 18.3, 23.3 and 28.3 MeV within the angular range of θc:m: ≈ 15◦ s 80◦. The analyse of these angular distributions together with the data taken from literatures at Elab(7Li) = 34 MeV have been performed to extract the parameters of optical model potential. With the fixed geometrical shapes, the potential strengths show a concise relation to the reaction energy: the depths of real potential decrease linearly with energy increasing, whereas the depths of imaginary part just slightly vary around the average value of 10.35 MeV.
