摘要:Abstract(#br)Total and differential cross sections for the reactions p + d → 3 He + m 0 with m = π, η and p + d → 3 H+π + were measured with the GEM detector at COSY for beam momenta between threshold and the maximum of the corresponding baryon resonance. For both react...

摘要:Abstract(#br)The paper describes modifications of the Jülich magnetic spectrometer Big Karl needed to study meson production and especially to investigate charge symmetry breaking effects—an experiment that requires a high-precision measurement. New elements that have been a...

摘要:Abstract(#br)We performed a series of experiments employing the two pion production reactions p + d → 3 He + π 0 and p + d → 3 H + π + . The two isopin related reactions differ by a Clebsch Gordan coefficient of 2. We searched for deviations in this ratio in complete an...

摘要:Abstract(#br)Recent improvements in the performance of PbWO 4 , a high-density inorganic scintillator, offer the possibility to design very compact, large-acceptance electromagnetic calorimeters with excellent timing and good energy resolution, applicable also for photon ene...
