A bubble chamber experiment to measure the polarization of the recoil proton in the photoproduction of π0 mesons from hydrogen

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

A rapid cycling bubble chamber is used to measure the polarization of the recoil proton from the reaction γ+p→π0+p. The experimental setup and the method of analysis of the events are described. We give a preliminary result of the polarization for a mean photon energyk=725 MeV and a center of mass angle of 87°.

Riassunto

Una camera a bolle a ciclo rapido è stata adoperata per misurare la polarizzazione del protone di rinculo della reazione γ+p→π0+p. Vengono descritte la disposizione sperimentale e il metodo di analisi degli eventi. Si dà il risultato preliminare per la polarizzazione a un’energia media dei fotonik=725 MeV e ad un angolo di emissione nel sistema del baricentro di 87°.
