Nuclear astrophysics
Roland Diehl, Michael Wiescher
Reactions between atomic nuclei are measured in great detail in terrestrial laboratory experiments; transferring and extrapolating this knowledge to how the same reactions act with…
Tracing the ejecta from cosmic nucleosynthesis
Roland Diehl
Long-lived radioactive by-products of nucleosynthesis provide an opportunity to trace the flow of ejecta away from its sources for times beyond where ejecta can be seen otherwise.…
Radioactive Decay
Roland Diehl
Radioactive decay of unstable atomic nuclei leads to liberation of nuclear binding energy in the forms of gamma-ray photons and secondary particles (electrons, positrons); their en…
Galactic annihilation emission from nucleosynthesis positrons
P. Martin, A. W. Strong, P. Jean +2
The Galaxy hosts a widespread population of low-energy positrons revealed by successive generations of gamma-ray telescopes through a bright annihilation emission from the bulge re…
The sky distribution of 511 keV positron annihilation line emission as measured with INTEGRAL/SPI
G. Weidenspointner, J. Knoedlseder, P. Jean +10
The imaging spectrometer SPI on board ESA's INTEGRAL observatory provides us with an unprecedented view of positron annihilation in our Galaxy. The first sky maps in the 511 keV an…
