Problems of identification of recoil particles in the S143 experiment
Description
The experiment performed in the South Hall at CERN by the collaboration Clermont-Ferrand, Lyon, Uppsala, Varsovie is briefly described. The aim of this experiment is to show the isobaric states which could preexist in the nucleus by using 5GeV pions on helium 4. One shows how to identify the recoiling nuclei by using only the recoiling apparatus. The recoil spectrometer has two arms placed symmetrically around the target; each arm consists of four planes of multiwire proportional chambers, two planes of 8 semiconductor detectors and two plastic scintillators (20mm and 8mm thickness). A forward spectrometer is also used, the components of which are a CERN standard bending magnet, two blocks of MWPC in front of this magnet and two blocks behind it

On decrit brievement l'experience realisee dans le Hall Sud du CERN par une collaboration Clermont-Ferrand, Lyon, Uppsala, Varsovie. Le but de cette experience est de montrer les etats isobariques qui peuvent preexister dans le noyau, en utilisant des pions de 5GeV sur une cible d'helium 4. On montre comment identifier les noyaux de recul en utilisant seulement un appareillage de recul. Le spectrometre de recul a deux bras places symmetriquement autour de la cible; chaque bras consiste en quatre plans de chambres proportionnelles multifils, deux plans de 8 semiconducteurs et deux scintillateurs plastiques (20mm et 8mm d'epaisseur). On utilise aussi un spectrometre avant, constitue d'un aimant standard du CERN, de deux blocs de chambres multifils devant cet aimant, et deux blocs derriereFiles
