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...

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,...

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...

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,...
