Abstract
In this paper we describe the results of the analysis of the photodisintegration and π± photoproduction processes in nitrogen obtained by exposing a diffusion cloud chamber in a magnetic field to the γ-ray beam of the Frascati synchrotron (Eγmax=1000 MeV). The value of the cross section obtained per equivalent quantum and per nucleon for π± photoproduction is in agreement with that estimated per free nucleon.
