Description
High resolution hypernuclear gamma-ray spectroscopy is very
useful for a complete understanding of the hyperon-nucleon
interaction at low energy. In particular, the precise
determination of the strength of the spin-dependent terms of the
interaction potential can be assessed
experimentally for simple systems like p-shell hypernuclei.
The FINUDA experiment, running at DAFNE, is completely dedicated
to hypernuclear physics studies. The apparatus can be upgraded by
adding to the present setup the capability of detecting gamma
rays emitted
during the deexcitation of the produced hypernuclei, without
renouncing to its very good figures of momentum resolution and
angular acceptance.
FINUDA could become the most complete and performing magnetic
spectrometer even dedicated to hypernuclear physics.
The project of integrating high resolution gamma rays detectors
inside the FINUDA tracking system will be discussed, considering
both the problem
of operating Ge detectors inside high magnetic field and in
presence of high particles rate and the required mechanical
modifications.
