Measurement of the Absolute Branching Fraction of D0 -> K- pi+

We measure the absolute branching fraction for $D0 \to K^{-} \pi^{+}$ using partial reconstruction of $B0bar \to D^{*+} X \ell^{-} \bar{\nu}_{\ell}$ decays. Only the charged lepton and the soft pion from the decay $D^{*+} \to D^{0} \pi^{+}$…

Femtosecond reduction of atomic scattering factors triggered by intense x-ray pulse

X-ray diffraction of silicon irradiated with tightly focused femtosecond x-ray pulses (photon energy: 11.5 keV, pulse duration: 6 fs) was measured at various x-ray intensities up to $4.6\times10^{19}$ W/cm$^2$. The measurement reveals that…

Far-infrared probe of superconductivity in SmO$_{1-x}$F$_{x}$FeAs}

We report far-infrared reflectance measurements on polycrystalline superconducting samples of SmO$_{1-x}$F$_{x}$FeAs ($x$ = 0.12, 0.15 and 0.2). We clearly observe superconductivity induced changes of reflectivity in a broad range of…

Fano effect in the $a-b$ plane of Nd$_{1.96}$Ce$_{0.04}$CuO$_{4+y}$: evidence of phonon interaction with a polaronic background

Reflectance measurements in properly selected samples of Nd$_{1.96}$Ce$_{0.04}$CuO$_{4+y}$ with different carrier concentrations provide a firm evidence of Fano antiresonances for the four transverse optical $E_u$ phonons in the $a-b$…

Absolute calibration of fiber-coupled single-photon detector

We show a setup for characterising the efficiency of a single-photon-detector absolutely and with a precision better of 1%. Since the setup does not rely on calibrated devices and can be implemented with standard-optic components, it can be…

Photon flux determination of a liquid-metal jet x-ray source by means of photon scattering

Liquid-metal jet X-ray sources promise to deliver high photon fluxes, which are unprecedented for laboratory based X-ray sources, because the regenerating liquid-metal anode is less sensitive to damage caused by an increased electron beam…
