FINUDA - A Detector for Nuclear Physics at DAFNE (out of print esaurita)

We propose the construction of a detector dedicated to Nuclear Physics studies, called FINUDA, at DAFNE, the Frascati ∅-Factory. The initial physics program is focused on the spectroscopy and decay modes of Λ-hypernuclei, which are produced following of tagged K⁻ in nuclear targets. The unique property of kaons at DAFNE, coupled to the expected performances of FINUDA (momentum resolution of 0.2% FWHM, and dedicated triggers) will allow an unprecedented step forward concerning the precision of the measurements and, even more, the counting rates. At l = 10^32 cm^-2 s^-1 we expect to produce and carefully study about 20 hypernuclei, most of them new. The puzzling situation regarding the validity of the ΛI=1/2 rule for non-mesonic decays of hypernuclei will be hopefully clarified. FINUDA could also be used for measurements on low K=N interaction.
