Gamma-ray emission from individual classical novae
Gamma-ray emission from individual classical novae
Classical novae are important producers of radioactive nuclei, such as 7Be, 13N, 18F, 22Na and 26Al. The disintegration of these nuclei produces positrons (except for 7Be) that through annihilation with electrons produce photons of energies 511 keV and below. Furthermore, 7Be and 22Na decay producing photons with energies of 478 …
