title = "Interpreting the 1 to 10 MEV gamma-ray background",
abstract = "The origin of the 1 to 10 MeV feature in unknown. Indeed, the origin of the entire X and gamma-ray backgrounds remains enigmatic. The gamma-ray background (from about 200 keV to at least 100 MeV) appears to be well matched by a power law, with one nonpower law feature: the 1 to 10 MeV feature. Here, we present and discuss a functional form which fits the 1 to 10 MeV feature exceedingly well. Theoretical interpretations of this fit are discussed.",

note = "Funding Information: As described above, the gamma ray back\textasciitilde{}-ound from about 200 keV to 1 MeV and from 10 MeV to at least 100 MeV is described by a single power law given by I Ip (e0) = 1.1 {\texttimes} 10 -2 \textbackslash{}[E0(MeV)\textbackslash{}-] 23 photons MeV -1 cm -2 s -1 sr -1 where Eo is the photon energy at a redshift of zero. It seems most reasonable to assume that this power law continues between 1 and 10 MeV, so that the 1 to 10 MeV feat'\textasciitilde{}re is superposed on this underlying power law. Then \textasciitilde{}he spectrum of the I to 10 MeV feature is obtained by subtracting the power law from the total specific intensity. We shall assume that the 1 to 10 MeV feature may be described by II(,,o(E,) = k,T, --o\textasciitilde{}1/\textasciitilde{} e-(\textasciitilde{}Eo){"}', or Iy(,)(Eo) = kr Eo • -(\textasciitilde{}°)2.
