Description
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, compared to large
statistical noise of the kink search in the usual electron spectrum.
I'll discuss advantages and problems of this approach.
