Single Boson Images Via an Extended Holstein Primakoff Mapping

Zoheir Aouissat

The Holstein-Primakoff mapping for pairs of bosons is extended in order to accommodate single boson mapping. The proposed extension allows a variety of applications and especially…

Two Proton Emission in the Hyperspheric Harmonics Approach

Ivan Mukha

Nuclear decays into three-particle channels are considered in a few-body approach of hyperspherical harmonics with emphasis on simultaneous, or direct, emission of two protons. Gen…

Electroweak Gauge Bosons at Future Electron-Positron Colliders

Thorsten Ohl

The interactions of electroweak gauge bosons are severely constrained by the symmetries inferred from low energy observables. The exploration of the dynamics of electroweak symmetr…

First Experimental Evidence for Chaos-Assisted Tunneling in a Microwave Annular Billiard

C. Dembowski, H. -D. Graef, A. Heine +3

We report on first experimental signatures for chaos-assisted tunneling in a two-dimensional annular billiard. Measurements of microwave spectra from a superconducting cavity with…

The Longitudinal and Transverse Response of the 4He(e,e'p) Reaction in the Dip Region

A1 Mainz Helium Collaboration, A. Kozlov

A high-resolution study of the (e,e'p) reaction on Helium-4 was carried out at the Institut fuer Kernphysik in Mainz, Germany. The measurements were done in parallel kinematics (mo…

A Measurement of the Coulomb Dissociation of 8B at 254 MeV/nucleon and the 8B Solar Neutrino Flux

N. Iwasa, F. Boue, G. Surowka +29

We have measured the Coulomb dissociation of 8B into 7Be and proton at 254 MeV/nucleon using a large-acceptance focusing spectrometer. The astrophysical S17 factor for the 7Be(p,ga…
