The FINUDA detector has been installed at the (e(+), e(-)) collider DAPhiNE at Laboratori Nazionali di Rascati (Italy). The commissioning of the detector was started and will be immediately followed by a data taking run with targets of Li-6, Li-7, C-12, Al-27 and V-51. Hypernuclei of the same A as the target nuclei will be copiously produced by means of the strangeness exchange reaction by stopped K-. The aim of the experiment is to measure simultaneously excitation energy spectra with a resolution better than 1 MeV, lifetime of the Lambda in the different Hypernuclei, partial decay widths Lambda(pi), Lambda(np) and Gamma(nn) for mesonic and non-mesonic decays, in coincidence. Further information could be gained on neutron-rich Hypernuclei and rare two-body decays. Ideas for the continuation of the program, as well as possible extension to an improved machine (DAPhiNE2) will be finally discussed.

Abstract
The FINUDA detector has been installed at the (e(+), e(-)) collider DAPhiNE at Laboratori Nazionali di Rascati (Italy). The commissioning of the detector was started and will be immediately followed by a data taking run with targets of Li-6, Li-7, C-12, Al-27 and V-51. Hypernuclei of the same A as the target nuclei will be copiously produced by means of the strangeness exchange reaction by stopped K-. The aim of the experiment is to measure simultaneously excitation energy spectra with a resolution better than 1 MeV, lifetime of the Lambda in the different Hypernuclei, partial decay widths Lambda(pi), Lambda(np) and Gamma(nn) for mesonic and non-mesonic decays, in coincidence. Further information could be gained on neutron-rich Hypernuclei and rare two-body decays. Ideas for the continuation of the program, as well as possible extension to an improved machine (DAPhiNE2) will be finally discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
