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.
