A study of nuclear interactions caused by negative pions

During the last many years, the work on high energy experiments was carried out by many workers mostly for shower particles which are fast moving particles or we can say that relativistic charged particles in hadron-nucleus (hA) and nucleus-nucleus (AA) collisions. The investigation of hA collisions is fundamental for understanding the nature of the interaction process. It is believed that these interactions may provide some very useful information about the dynamics of multiparticle production. An important feature noticed in these interactions is that the nucleus plays the role of target for the incident hadron. When an incident particle interacts with the nuclei of the emulsion, secondary particles are produced. In the present paper the data was collected using a stack exposed to a 340 GeV negative pion beam
