Abstract
It is possible to predict the amount of gamma rays which are produced in various astronomical objects = gamma rays due to nuclear reactions, to bremsstrahlung, to cosmic rays, to annihilation of matter and anti-matter. These predictions are compared to the results of the observations with Explorer XI and are used to suggest new experiments. The following experiments are suggested:
-
(1)
to measure the γ flash associated with Supernovae;
-
(2)
to study the energy spectrum of γ rays from radio-sources;
-
(3)
to study the γ rays produced in the galaxy, in the halo, and in extragalactic nebulae.
The weight of the instruments is sufficiently low to put γ astronomy among the immediate program of European space research.
