AbstractΛ-hypernuclei are produced and studied, with the FINUDA spectrometer, for the first time at an e + e − collider: DAΦNE, the Frascati φ-factory. The slow negative kaons from φ(1020) decay are stopped in thin (0.2 g/cm 2 ) nuclear targets, and Λ-hypernuclei formation is detected by measuring the momentum of the outgoing π − . A preliminary analysis on 12 Λ C shows an energy resolution of 1.29 MeV FWHM on the hypernuclear levels, the best obtained so far with magnetic spectrometers at hadron facilities. Capture rates for the ground state and the excited ones are reported, and compared with previous experiments.PACS: 21.80.+a

“…A system of six stereo-arranged layers of straw tubes (ST) is the last position sensitive tracking device located within the magnetic field [12]. The outermost layer of FINUDA, TOFONE, consists of 72 trapezoidal slabs of plastic scintillator [13]. TOFONE is the stop-counter of the FINUDA time-of-flight measurements and also measures the energy released by charged particles and neutrons.…”

Novel data from the K − stop A absorption reaction in light nuclei 6,7 Li and 9 Be are presented. The study aimed at finding Λt correlations. Regardless of A, the Λt pairs are preferentially emitted in opposite directions. Reaction modeling predominantly assigns to the K − stop A → Λt(N )A ′ direct reactions the emission of the Λt pairs whose yield is found to range from 10 −3 to 10 −4 /K − stop . The experiment was performed with the FINUDA spectrometer at DAΦNE (LNF). :21.45.+v, 21.80.+a 25.80.Nv PACS

“…This stereo device is the last layer used for particle localization. The outermost layer of FINUDA consists of a segmented detector, TOFONE, made of rectangular slabs of plastic scintillator [15]. TOFONE is designed as the stop for the FINUDA time-of-flight measurements and also measures the energy released by charged particles.…”
