Journal ArticleDOI
Partial Time-Reversal Invariance Violation in a Flat, Superconducting Microwave Cavity with the Shape of a Chaotic Africa Billiard.
TL;DR: In this article, a flat, superconducting microwave resonator, a microwave billiard, with partially violated time-reversal invariance, induced by inserting a ferrite into the cavity and magnetizing it with an external magnetic field perpendicular to the resonator plane was presented.
Journal ArticleDOI
Uncommon decay branching ratios of spin-one states in the rare-earth region and evidence for K mixing.
TL;DR: The examination of 171 levels found in NRF experiments yields that most values of {ital R}{sub exp} are in good agreement with the Alaga rules, Nevertheless, some branching ratios suggest a possible mixing of{ital K} values.
Journal ArticleDOI
R-matrix theory of driven electromagnetic cavities.
TL;DR: The resonances of cylindrical symmetric microwave cavities are analyzed in R-matrix theory, which transforms the input channel conditions to the output channels, and give insight into the resonance structure of regular and chaotic quantum billiards.
Journal ArticleDOI
Systematics of the pygmy dipole resonance in stable tin isotopes from resonant photon scattering
B. Özel,B. Özel,Joachim Enders,P. von Neumann-Cosel,I. Poltoratska,Achim Richter,Deniz Savran,Stephan Volz,Andreas Zilges +8 more
TL;DR: In this article, the pygmy dipole resonance (PDR) in stable Sn nuclei was analyzed for different endpoint energies of the incident bremsstrahlung spectrum below the neutron separation energies at the superconducting Darmstadt electron linear accelerator S-DALINAC.
Journal ArticleDOI
Bound states in sharply bent waveguides: Analytical and experimental approach
Stefan Bittner,Barbara Dietz,M. Miski-Oglu,Achim Richter,C. Ripp,Emerson Sadurni,Emerson Sadurni,Wolfgang P. Schleich +7 more
TL;DR: The bound states are computed, the features of the transition from a bound to an unbound state caused by the variation of the bending angle are studied, and the critical bending angles at which such a transition takes place are determined.
