Observation of Celestial Gamma Rays,t are sufficiently sensitive for the measurement of these very weak fluxes. The very large scientific interest for these observations comes from the fact that, although gamma rays originate also from interactions of electrons with particles and fields, they are both created in nuclear interactions v

Supernovae and the Origin of Cosmic Rays (II) , A Model of Cosmic Ray Production in Supernovae, I or II supernovae, but at least outlined the difference between these; namely that the Type I’s occur in old population stars, have a rapid rise time, and show no hydrogen in their spectra, and Type II supernovae appear in young Type I population stars, have much slower rise in light curves and sl

Gamma Ray Astrophysics, answered at this point in time, given our relatively primitive observations and the context of our present theoretical understanding. Thus, of necessity, we will spend most of our time here discussing the origin of the gamma radiation itself, bearing in mind the relation of this problem with that o

The Galaxy and Interstellar Medium,s made to solve the problem of covering such a broad subject in a brief review by concentrating on those features which are judged to have a direct bearing on the origin and propagation of cosmic rays. Even so it is not feasible to support the text fully with references. A suggested reading list is therefore given at the end.

,Nuclear Mass Composition at ‘Low’ Energies (i.e.< 1012eV/Nucleon),ing processes that take place inside stars during their evolution, and that the composition of the nuclear cosmic rays is one of the most important sources of information about the nucleosynthesis in the stars and the composition of matter in important regions of our galaxy.
