The gamma rays are mainly from inverse Compton scattering emission, and the DM cascade annihilation could be compatible with joint astrophysical limits and meanwhile be allowed by AMS-02 positron observation. The direct detection of this model is also discussed."> Interpretation of the Galactic gamma-ray excess with the dark matter indicated by <sup>8</sup>Be and <sup>4</sup>He anomalous transitions -
