Description
The continuity equation for cosmic ray propagation is used to derive a set of linear equations interrelating the fluxes of multiply charged nuclei as observed at any particular part of the galaxy. The derivation leads to model indepent definitions for cosmic ray storage time, mean density of target nuclei and effective mass traversed. The set of equations form a common framework for comparisons of theories and observations. As an illustration, it is shown that there exists a large class of propagation models which give the same result as the exponential path length model. (orig./BJ)
Abstract (German)
Die Kontinuitaetsgleichung fuer die Ausbreitung kosmischer Strahlung wird benutzt, um einen Satz linearer Gleichungen abzuleiten, mit denen die Fluesse vielfach geladener Kerne, wie man sie in jedem speziellen Teil der Galaxis beobachten kann, verknuepft werden. Die Ableitung fuehrt auf modellunabhaengige Definition fuer die Speicherzeit der kosmischen Strahlung, die mittlere Dichte der Targetkerne und die effektive durchquerte Masse. Der Gleichungsatz bildet einen allgemeinen Rahmen fuer Vergleiche zwischen Theorien und Beobachtungen. Als Illustration wird gezeigt, dass es eine grosse Klasse von Ausbreitungsmodellen gibt, die zum selben Ergebnis fuehren wie das Modell der exponentiellen Weglaenge. (orig./BJ)Additional details
