The propagation of ultraheavy cosmicray nuclei revisited
Abstract
The propagation of ultraheavy (Z = 30 or more) cosmicray nuclei is investigated theoretically in the leakybox model, expanding the analysis of Brewster et al. (1983) to include more individual nuclides and account for recent findings with respect to source compositions, cross sections, and the dependence of escape length and spectral characteristics on rigidity. The results of numerical computations are presented in tables and graphs and compared with observational data (from HEAO3) and other theoretical predictions. Good agreement is obtained for Z = 3242 and 5058 using a solarsystem source with a firstionizationpotential correlation factor and the solarsystem abundances given by Anders and Ebihara (1982).
