Abstract:

A method of analysing the data of high energy jet showers in nuclear emulsions is proposed. We discuss the possibilities to reduce the nucleon-nucleon collisions to pion-nucleon interactions. If we use the experimental data on π--p collision at 5 Gev as the pion-nucleon interaction, we can estimate the energy and angular distribution of emitted pions in rather low energy jet showers (\lesssim 100 Gev) and the obtained results fairly agree with the experiments. As to the high energy jet showers (\gtrsim 100 Gev) we can conclude that almost all of collisions are regarded as peripheral ones and that the properties of the pion-nucleon interaction reduced from the nucleon-nucleon collision are similar to those of the pion-nucleon interaction actually observed. It is also suggested that the nucleon has a core whose radius is about a nucleon Compton wave length.
