High-resolution measurement of dielectronic recombination of lithiumlike Cu26+
Energies and absolute cross sections for dielectronic recombination of lithiumlike Cu 26+ via ΔN=0 and ΔN=1 resonances have been measured at the Heidelberg heavy-ion storage ring TSR employing theExpand

All materials behave like stacks of superconductor-insulator-superconductor Josephson junctions, and the current-voltage characteristics exhibit large hystereses and multiple branches. Expand

The results for a massless, minimally coupled scalar field can be summarized by $S_{ent}=0.30 r_H^2/a^2$, which resembles the flat space formula, although here the horizon radius, $r_H$, is time-dependent. Expand
Tensor LEED: A technique for high-speed surface-structure determination.
Quantum Statistics of the Squeezed Vacuum by Measurement of the Density Matrix in the Number State Representation.
The reconstruction of the quantum state of squeezed vacuum generated by a continuous-wave optical parametric amplifier is reported, and the photon number distribution exhibits odd-even oscillations, a manifestation of the photon pair production in the second-order nonlinear medium. Expand
Improved constraint on the alpha 1 PPN parameter from lunar motion.
Following previous theoretical suggestions, it is shown that the analysis of the lunar motion provides an improved bound of the former parameter a1 anda2, of which only the latter is strongly constrained today. Expand
Ferroelectric relaxation of the SrTiO3(100) surface.
Long-wavelength collective excitations of charge carriers in high-Tc superconductors.
Nucleosynthesis and Clump Formation in a Core-Collapse Supernova.
It is found that newly formed iron-group elements are distributed throughout the inner half of the helium core by Rayleigh-Taylor instabilities at the (Ni + Si)/O and (C + O)/He interfaces, seeded by convective overturn during the early stages of the explosion. Expand
Cosmic ray positrons at high energies: A new measurement.
Using a magnet spectrometer combined with a transition radiation detector, an electromagnetic calorimeter, and time-of-ight counters, a high degree of background rejection is achieved of the cosmic-ray positron fraction e + =(e + + e) obtained from the HeAT. Expand
