Table 2
Integrated 4.44 MeV line flux under different assumptions of n and χ.
| n | χ | Flux |
|---|---|---|
| (cm−3) | (photon cm−2 s−1) | |
| 1 | 1.0 | 5.49 × 10−9 |
| 1 | 0.1 | 3.25 × 10−8 |
| 1 | 0.01 | 1.25 × 10−7 |
| 100 | 1.0 | 1.25 × 10−7 |
| 100 | 0.1 | 3.16 × 10−7 |
| 100 | 0.01 | 5.96 × 10−7 |
Notes. The injection rate of protons Q∕d2 = 1038erg s−1 kpc−2 and spectral index s = 2.0 are assumed. The FWHM width of 4.44 MeV narrow line ΔE is ~ 100 keV. Details is described in Sect. 3.2.
