This thesis is divided into two parts. In Section I a description is given of a liquid hydrogen bubble chamber expansion system designed for use with the Imperial College 40cm. hydrogen chamber, and as a prototype system for the 150 cm. British National chamber. Section II contains a study of - proton interactions at an incident pion momentum of 4 Gev/c. The Saclay 81cm. liquid hydrogen bubble chamber was exposed to a beam from the CERN proton synchroton, and produced 60,000 useful pictures. The analysis of those events with two charged secondaries, excluding strange particle events, is presented. Chapter II reviews the background to and objectives of the experiment. In Chapter III an account is given of the apparatus and methods used in the processing of the film. The individual identification of events is described in Chapter IV. Cross-sections, angular and momentum distributions, and resonance production for the different reaction channels are presented and discussed in Chapters V and VI. Finally in Chapter VII, a brief description is given of some preliminary results of an investigation of +-proton interactions of 4Gev/c.
