| 1 | High spin states in stable nucleus ^(84)Sr显示文摘High spin states of 84Sr were populated through the reaction 70Zn(18O,4n)84Sr at 75 MeV beam energy.Measurement of excitation function,γ-γ coincidences,directional correlation from oriented state (DCO) ratios and γ-transition intensities were performed using eight anticompton HPGe detectors and one planar HPGe detector.Based on the measured results,a new level scheme of 84Sr was established in which 12 new states and nearly 30 new γ-transitions were identified in the present work.The positive-parity states of the new level scheme were compared with the results from calculations in the framework of the projected shell model (PSM).One negative-parity band was extended to spin Iπ=19-and it can be found that in the high spin states,the γ-transition energies show the nature of signature staggering.The negative-parity band levels are in good agreement with deformed configuration-mixing shell model (DCM) calculations. | KANG XuZhong1,2,SHEN ShuiFa1,2,3,4*,HAN GuangBing5,PAN Feng3,4,GU JianZhong6,DRAAYER J P4,WU XiaoGuang6,ZHU LiHua6 & WEN TingDun7 1 Key Laboratory of Nuclear Resources and Environment (East China Institute of Technology),Ministry of Education,Nanchang 330013,China 2 School of Nuclear Engineering and Technology,East China Institute of Technology,Fuzhou 344000,China 3 Department of Physics,Liaoning Normal University,Dalian 116029,China 4 Department of Physics and Astronomy,Louisiana State University,Baton Rouge,LA 70803-4001,USA 5 School of Physics,Shandong University,Jinan 250100,China 6 China Institute of Atomic Energy,Beijing 102413,China 7 Department of Physics,North University of China,Taiyuan 030051,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，10： | 4 |
| 2 | Novel ^(99m)Tc labeled σ r eceptor ligand as a potential tumorimaging agent显示文摘A novel 99mTc labeled complex, [N-[2-((2-oxo-2-(4-(3-phenylpropyl)piperazin-1-yl)ethyl) (2-mercaptoethyl)amino)acetyl]-2-aminoethanethiolato]Technetium(V) oxide (PPPE-MAMA′-99mTcO) ([99mTc]-2) has been designed and prepared based on the integrated approach. The corresponding rhenium complex (PPPE-MAMA′-ReO)(Re-2) has been prepared and characterized. In vitro competi-tion binding assays show moderate affinity of Re-2 towards σ1 and σ2 receptors with Ki values of 8.67 ± 0.07 and 5.71 ± 1.88 μmol, respectively. Planar images obtained at 0.5 h, 4 h, 20 h after i.v. in-jection indicate the accumulation of [99mTc]-2 in MCF-7 human breast tumor bearing mice at 20 h. Furthermore, the accumulation of [99mTc]-2 has been inhibited at 20 h after co-injection of [99mTc]-2 plus haloperidol (1 mg/kg). Biodistribution studies of [99mTc]-2 display an in vivo tumor uptake of 0.14% ± 0.01% ID/g at 24 h post i.v. injection with a tumor/muscle ratio of 6.02 ± 0.87. The above results suggest that [99mTc]-2, derived from a previously published lead compound, retains certain tumor uptake and affinity for σ receptors. [99mTc]-2 may be used as a basis for further structural modifications to develop tumor imaging agents with high affinity for σ receptors. | FAN Caiyun1, JIA Hongmei1, Deuther-Conrad Winnie2, Brust Peter2, Steinbach J?rg2 & LIU Boli1 1.

| 12 | Impact of Mining Activities upon Environment in Panzhihua Region, Southwestern China显示文摘Mining activities have left huge uncovered slopes, large areas of gangue ground and extensive railings dams. In this paper, we studied some impacts of mining activities upon environment in Panzhihua region, southwestern China. The environmental impacts include ecological destruction, geological disasters, environmental pollution, land damage, solid waste and occupational health effect in study area. The author suggested that local government should take some measure to reduce environmental impact in Pan... | TENGY~1, NIS~2, WANG J~1, ZHANG C~2 XU Z~2,TUO X~2 (1.
