Design and Construction of the BESIII Detector
The BESIII Collaboration
This paper will discuss the design and construction of BESIII, which is designed to study physics in the tau-charm energy region utilizing the new high luminosity BEPCII double rin…
Continuous metal-insulator transition of the antiferromagnetic perovskite NaOsO3
Y. G. Shi, Y. F. Guo, S. Yu +11
Newly synthesized perovskite NaOsO3 shows Curie-Weiss metallic nature at high temperature and suddenly goes into an antiferromagnetically insulating state at 410 K on cooling. Elec…
Structural properties and superconductivity of SrFe2As2-xPx and CaFe2As2-yPy
H. L. Shi, H. X. Yang, H. F. Tian +5
The SrFe2As2-xPx and CaFe2As2-yPy materials were prepared by a solid state reaction method. X-ray diffraction measurements indicate the single-phase samples can be successfully obt…
Phase separation and ferroelectric ordering in charge frustrated LuFe2O4-x
H. X. Yang, H. F. Tian, Y. Zhang +6
The transmission electron microscopy observations of the charge ordering (CO) which governs the electronic polarization in LuFe2O4-x clearly show the presence of a remarkable phase…
Study of J/Psi decays into eta Kstar Kstar-bar
The BES Collaboration, M. Ablikim
We report the first observation of $\mPJpsi \to \mPeta\mPKst\mAPKst$ decay in a $\mPJpsi$ sample of 58 million events collected with the BESII detector. The branching fraction is d…
value measurements for annihilation at 2.60, 3.07 and 3.65 GeV
The BES Collaboration, M. Ablikim
Using a data sample with a total integrated luminosity of 10.0 pb collected at center-of-mass energies of 2.6, 3.07 and 3.65 GeV with BESII, cross sections for anni…
