Precison Measurements of the Mass, the Widths of $ψ (3770)$ Resonance and the Cross Section $σ [e^{+} e^{-} \to ψ (3770)]$ at $E_{cm} = 3.7724$ GeV

M. Ablikim et al.

By analyzing the $R$ values measured at 68 energy points in the energy region between 3.650 and 3.872 GeV reported in our previous paper, we have precisely measured the mass, the t…

Unraveling electronic-structure features for metallic Na0.33CoO2 and charge-ordered Na0.5CoO2 by high-resolution electron energy-loss spectroscopy

R. J. Xiao, J. H. Chen, H. X. Yang +4

Measurements by high-resolution electron energy-loss spectroscopy (HREELS) of NaxCoO2 reveal spectral features that differ remarkably between the metallic Na0.33CoO2 and the charge…

Electronic structure and electron energy-loss spectra of Sr0.35CoO2

R. J. Xiao, H. X. Yang, L. F. Xu +3

The electronic structure of Sr0.35CoO2, structurally analogous to the layered NaxCoO2, has been evaluated using the local spin density approximation (LSDA). We find that evident c-…

Direct measurement of the absolute branching fraction for $D^{+} \to K ˉ^{0} μ^{+} ν_{μ}$ and determination of $Γ (D^{0} \to K^{-} μ^{+} ν_{μ}) /Γ (D^{+} \to K ˉ^{0} μ^{+} ν_{μ})$

M. Ablikim

The absolute branching fraction for the decay $D^{+} \to K ˉ^{0} μ^{+} ν_{μ}$ is determined using $5321 \pm 149 \pm 160$ singly tagged $D^{-}$ sample from the data collected around 3.773 G…

Measurements of the cross sections for $e^{+} e^{-} \to hadrons$ at 3.650, 3.6648, 3.773 GeV and the branching fraction for $ψ (3770) \to non - D D ˉ$

M. Ablikim et al.

Using the BES-II detector at the BEPC Collider, we measured the lowest order cross sections and the $R$ values ( $R = σ_{e^{+} e^{-} \to hadrons}^{0} / σ_{e^{+} e^{-} \to μ^{+} μ^{-}}^{0}$ ) for incl…

Correlations among superconductivity, structural instability, and band filling in Nb1-xB2 at the critical point x=0.2

R. J. Xiao, K. Q. Li, H. X. Yang +5

We performed an extensive investigation on the correlations among superconductivity, structural instability and band filling in Nb1-xB2 materials. Structural measurements reveal th…
