Charged-particle multiplicity and transverse energy in Pb-Pb collisions at sqrt(snn) = 2.76 TeV with ALICE
Charged-particle multiplicity transverse energy Pb-Pb collisions
2011/7/21
The measurements of charged-particle multiplicity and transverse energy at mid-rapidity in Pb-Pb collisions at sqrt(sNN) = 2.76 TeV are reported as a function of centrality. The fraction of the inelas...
D meson nuclear modification factors in Pb-Pb collisions at {\surd}sNN = 2.76 TeV, measured with the ALICE detector
D meson nuclear Pb-Pb collisions ALICE detector
2011/7/21
The ALICE experiment has measured the D meson production in pp and Pb-Pb collisions at the LHC at {\surd}s = 7 and 2.76 TeV and {\surd}sNN = 2.76 TeV respectively, via the exclusive reconstruction of ...
The transverse momentum spectra, elliptic flow and interferometry radii for Pb-Pb collisions at the LHC are calculated in relativistic viscous hydrodynamics. For Glauber model initial conditions, we f...
Charged particle directed flow in Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV measured with ALICE at the LHC
Charged particle directed flow Pb-Pb collisions sqrt ALICE
2011/7/20
Charged particle directed flow at midrapidity, |eta|<0.8, and forward rapidity, 1.7 < |eta|<5.1, is measured in Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV with ALICE at the LHC. Directed flow is report...
Resonance measurements in pp and Pb--Pb collisions with the ALICE detector
Resonance measurements pp Pb--Pb collisions ALICE detector
2011/7/21
The study of resonance production in pp collisions helps understanding hadronization mechanisms and tuning the QCD-inspired particle production models. In Pb--Pb collisions, resonances allow one to pr...
Heavy-flavour production in Pb-Pb collisions at the LHC, measured with the ALICE detector
Pb-Pb collisions LHC ALICE detector Heavy-flavour production
2011/7/20
We present the first results from the ALICE experiment on the nuclear modification factors for heavy-flavour hadron production in Pb-Pb collisions at sqrt{s_NN}=2.76 TeV. Using proton-proton and lead-...
源激发X射线荧光测定头发中Ca、Fe、Cu、Zn、Pb的方法优化
源激发X射线荧光 头发 V内标
2011/8/18
同位素源激发X射线荧光（XRF）已广泛应用于头发中的微量元素测定。中国原子能科学研究院曾经建立了源激发X射线荧光分析技术分析头发样品，Pb的检测限（LLD）约10 μg/g。本工作在原来工作的基础上优化仪器参数，降低背景信号强度，提高了灵敏度，尤其是对Pb的灵敏度，使Ca、Fe、Cu、Zn、Pb的检测限分别达到19、1.2、1.1、0.62、1.1 μg。首次采用V做内标元素，取样量为0.5 g，...
