A. Wirtzfeld,F. C. Himmler,H. Blömeresence in a characteristic .-ray line: positrons annihilate with their anti-particle (electrons) and convert the pair’s rest mass into a line at 511 keV (see Chap. 7). Nuclear energy levels range from 10 s of keV upwards to energies of 10 s of MeV with most important astrophysical lines in the range from about 100 keV to several MeV.

Book 20111st editionnt parts of the universe. The authors explain the role of radioactivities in astrophysics, discuss specific sources of cosmic isotopes and in which special regions they can be observed. More specifically, the authors address stars of different types, stellar explosions which terminate stellar evolut
