15. Spectral properties and scattering in chaotic billiards and nuclei*

Sufficiently flat microwave resonators ("microwave billiards") are well suited to study the quntum mechanical behavior of classically chaotic systems because of the formal equivalence of the respective wave equations, i.e. the Helmholtz and the Schroedinger equation. Using a superconducting 2-dimensional chaotic billiard ("stadium") as an example, it is shown that its spectral properties...

32. Status of the WITCH experiment

The WITCH experiment measures the energy spectrum of the recoil ions after nuclear beta decay. The radioactive ions are stored in Penning traps where they decay. The recoil spectrum is measured with a retardation spectrometer of MAC-E type. From the shape of the recoil spectrum the beta-neutrino angular correlation will be determined, with the goal to search for exotic interactions beyond the...

41. Oscillations of lepton number, double electron capture and atomic mass difference

Fedor Simkovic (Comenius University)

Oscillations of two neutral atoms, which proceed with the violation of lepton number, is proposed. One of the neutral atoms is stable, the other one represents a quasistationary state subjected to electromagnetic deexcitation. The underlying mechanism is a transitions of two protons and two bound electrons to two neutrons $p+p+e^-_b+e^-_b \leftrightarrow n+n$. A phenomenological...

45. PROTON-RICH IONS DECAYING BY EC: A SYNERGY BETWEEN NUCLEAR AND NEUTRINO PHYSICS

Esther Estevez Aguado (Instituto de Física Corpuscular (IFIC)-Universitat de València-U)

M. E. Estevez Aguado , A. Algora, J. Bernabeu, and B. Rubio (IFIC, CSIC-Uni. Valencia, Spain) Abstract: Neutrino oscillation studies have demonstrated that neutrinos have a mass and they mix. Next facilities will need pure, in flavour, and intense beams for very long-baseline experiments with massive detectors. The ultimate goal is the discovery and measurement of CP violation in the...
