Abstract

Preliminary results of the measurement of pd→ppnγγ reaction at around 1 GeV are presented. The reaction was measured at the CELSIUS storage ring using the WASA/PROMICE set-up. The quasi free mechanism was found to be dominant with Δ(1232) excitation in the proton-pion system. The signal at the position of Roper resonance was observed in the proton-π0 invariant mass. A class of “non-spectator” events was observed with small proton-proton invariant mass.

Abstract

The WASA 4π detector at the The Svedberg Laboratory in Uppsala is now being commissioned. This detector will make possible new detailed studies of many interesting rare processes in intermediate energy light-ion physics. WASA is built around a new target system, providing well defined internal hydrogen (and deuterium) targets of high density. It has a detection coverage of close to 4π sr for high energy photons and charged particles and it includes a strong magnetic field provided by an extremely thin-walled superconducting solenoid.

Abstract

The CLAMSUD spectrometer has been recently installed at the jet-target position of the CELSIUS ring at “THE SVEDBERG LABORATORY.” The physical purpose is the study of kaon production at energies below the N-N threshold. Due to the low cross-section and short lifetime of kaons we increased the solid angle by means of two quadrupoles positioned at the entrance of the dipole. The experimental quality of the measurements due both to the beam characteristics and to the CLAMSUD detector will be shown.

7. An overview of experimental trends and systematics in pion production and absorption in nuclei

Author

B. Höistad

Subjects
Nuclear physics, Nuclear reaction, Physics, Particle physics, Pion, Meson, Reaction dynamics, Hadron, Nuclear structure, Elementary particle, Boson
Abstract

An experimental overview of the (p,π) reaction on nuclei is given, emphasizing systematic behaviour in the data in general. Specific features in the data which point to nuclear structure dependence as well as in influence from the reaction dynamics are also discussed.
