A new way to explain the 511 keV signal from the center of the Galaxy and its possible consequences
, 2018 The first gamma-ray line originating from outside the solar system that was ever detected is the 511 keV emission from the center of our Galaxy. The accepted explanation of this signal is the annihilation of electrons and positrons.

The g Factor of a Bound Electron in a Hydrogen-Like Atom [PDF]
In Hydrogen atom: Precision physics of simple atomic systems. Ed.
by S. G. Karshenboim et al., (Springer, Berlin, Heidelberg, 2001) pp. 651-663, 2000 Recently, a precise measurement on the bound electron g factor in hydrogen-like carbon was performed [1]. We consider the present status of the theory of the g factor of an electron bound in a hydrogen-like atom and discuss new opportunities and possible applications of the recent experiment.
