Direct reactions and hauser-feshbach theory II numerical methods and statistical tests

Numerical methods and statistical tests are described which form part of a recent paper dealing with Hauser-Feshbach theory in the presence of direct reactions.     

Zur elektronenstruktur vicinaler triketone: Bicyclo[3.1.0]hexan-2.3.4-trione

Bicyclo[3.1.0]hexane-2.3.4-trione and its 1.5-dimethyl derivative have been synthesized and investigated by means of photoelectron spectroscopy.     

The importance of the fluctuating force for dissipative tunneling,examplified in a time-dependent picture

We exploit a time-dependent picture to compare the penetrability obtained from a multidimensional Schrödinger equation with the one from a Fokker-Planck equation. The result for the latter one is manifestly different. The origin of this difference is studied and traced back to the fluctuating force which accompanies dissipation, and which is present for open systems.     

Systematische Untersuchungen zum Optischen Modell der Deuteronenstreuung an24,26Mg und28,30Si

Differential cross sections for 10 MeV deuterons, elastically scattered from^24,26Mg and^28,30Si have been measured. The scattering data have been analysed systematically in the framework of the optical model. It was found, that an uniform set of parameters, which is able to reproduce reasonably the angular distributions for the four nuclei, does not exist. Both the Mg distributions as well as both the Si distributions, however, can be described well with one set of parameters, respectively.     

Demonstration of an optical quantum controlled-NOT gate without path interference

We report the first experimental demonstration of an optical quantum controlled-NOT gate without any path interference, where the two interacting path interferometers of the original proposals have been replaced by three partially polarizing beam splitters with suitable polarization dependent transmittance and reflectance. The performance of the device is evaluated using a recently proposed method, by which the quantum process fidelity and the entanglement capability can be estimated from the 32 measurement results of two classical truth tables, significantly less than the 256 measurement results required for full quantum tomography.
