Abstract : A model is proposed to explain a number of features of the differential rigidity spectra of the nuclear component of the primary cosmic radiation. A supernova explosion is assumed to result in the acceleration of nuclei to a pure power law rigidity spectrum and a composition relatively rich in heavy and medium weight nuclei. The supernova remnant into which these particles are injected is characterized as a large scale trapping region resulting from predominantly closed magnetic field lines which partially isolate the region from the surrounding galactic space. This feature of the supernova region is represented by a dipole-like field. Superimposed on this field we assume that magnetic irregularities produce a certain amount of distortion of the field lines in the interior of the source; and irregularities along the periphery of the source lead to local distortions of the field and hence, a mixing of galactic and source field lines in the neighborhood of these irregularities.
