Publisher's Synopsis
The importance of Ultra Heavy Nuclei in providing crucial information with regard to both the origin and propagation of cosmic rays is well known. Over the last few years, significant developments have taken place in the field due to close international co-operation in space activities. This volume contains information and new data on nuclear cross sections relevant to ultra heavy cosmic ray nuclei and their propagation through the interstellar medium. Continuing uncertainties present in propagation calculations are addressed, and propagation models relevant to the extrapolation of UH nuclei composition to the sources presented. The nucleosynthetic clues to the source characteristics and related ambiguities are also analyzed. Current concepts of shock acceleration are reviewed as is the fact that ultra heavy elements are siderophiles and preferentially concentrate in dust grains.
