Popis: A-hypenuclei are produced and studied, with the FINUDA spectrometer, for the first time at an e(+)e(-) collider: DA Phi NE, the Frascati phi-factory. The slow negative kaons from phi(1020) decay are stopped in thin (0.2 g/cm(2)) nuclear targets, and A-hypemuclei formation is detected by measuring the momentum of the outgoing pi(-). A preliminary analysis on C-12(Lambda) shows X 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. (c) 2005 Elsevier B.V. All rights reserved
