Exclusive πo- and η-meson production in 40Ar + natCa at 800A MeV

Abstract The impact-parameter dependence of π o - and η-meson production is reported for the system 40 Ar+ nat Ca at a beam energy of 800 A MeV. Scaling of the meson abundances with the transverse mass is observed. The experimental results are compared to calculations within the BUU model.

Detection of charged pions and protons in the segmented electromagnetic calorimeter TAPS

We present the characteristics of the segmented BaF2 calorimeter TAPS for the measurement of charged pions and protons. The method of particle identification exploits the relation between the kinetic energy of a particle, its mass and the time-of-flight required to reach the detector. The detection efficiency is calculated using GEANT-GCALOR simulations. The analysis method is applied in the reaction Ar-40 + Ca-nat at 0.8A GeV. The simultaneous detection of charged pions and protons can be used to search for correlated pairs signalling the de-excitation of the Delta(1232) resonance. (C) 1998 Elsevier Science B.V.
