3. Oscillations of Moessbauer neutrinos

Mr Joachim Kopp (Max Planck Institute for Nuclear Physics)

We discuss the phenomenology of the Mössbauer neutrino experiment proposed recently by Raghavan. In particular, we will show that Mössbauer neutrinos do oscillate, in spite of their extremely small energy uncertainty. Using a quantum field theoretical approach, we will compute the combined rate of Mössbauer neutrino production, oscillation and detection, and discuss the arising coherence...

4. One-dimensional ordering in high-energy ion beams

Dr Håkan Danared (Manne Siegbahn Laboratory)

A sudden reduction of momentum spread, and under certain conditions also of Schottky-noise power, has been observed with electron-cooled beams at a few ion storage rings. This has been interpreted as an effect of one-dimensional ordering of the beams, such that the ions line up after one another in the ring. A brief overview of subject of beam crystallization or beam ordering is given,...

5. Contribution of Penning trap mass spectrometry to neutrino physics

Dr Szilard Nagy (MPI-K)

08/12/2008, 09:50

Penning traps provide nowadays highest sensitivity, precision and accuracy for atomic mass spectrometry [1]. In the combined strong magnetic field and weak electric field of a Penning trap a charged particle can be stored and observed for long time thus frequency comparisons well below ppb can be performed. Different techniques such as non-destructive detection with...

6. Bounds on sterile neutrinos using full kinematic reconstruction of radioactive decays

Mr Fedor Bezrukov (MPI fur Kernphysik)

08/12/2008, 10:15

Current bounds on mixing angles for light (several keV range) sterile neutrinos are rather weak, though theoretically it is a very interesting region. An interesting experimental technique for analysing such neutrinos is full kinematic reconstruction of the nuclear beta decay. This method, in principle, allows an event by event measurement of the neutrino mass,...
