The Galactic Positron Annihilation Radiation & The Propagation of Positrons in the Interstellar Medium
J. C. Higdon, R. E. Lingenfelter, R. E. Rothschild
We consider positron propagation in the interstellar medium and show that the positrons from the beta-plus decay chains of the radioactive nuclei Ni-56, Ti-44, and Al-26, produced…

The Galactic 26Al Problem and The Close Binary SNIb/c Solution?
J. C. Higdon, R. E. Lingenfelter, R. E. Rothschild
The origin of the long-lived radioactive 26Al, which has been observed in the Galactic interstellar medium from its 1.809 MeV decay gamma-ray line emission, has been a persistent p…
