Proposal and theoretical formalism for studying baryon radiative decays   from J/\psi \to B^*\bar B + \bar{B^*}B \to \gamma B\bar B
  With accumulation of high statistics data at BESIII, one may study many new interesting channels. Among them, J/\psi \to B^*\bar B + \bar{B^*}B \to \gamma B\bar B processes may provide valuable information of the radiative decays of the excited baryons (N^*,\Lambda^*,\Sigma^*,\Xi^*), and may shed light on their internal quark-gluon structure. Our estimation for the branching ratios of the nucleon excitations N^*(1440), N^*(1535) and N^*(1520) from the reaction J/\psi \to N^*\bar p + \bar N^* p \to \gamma p\bar p, indicates that these processes can be studied at BESIII with 10^{10} J/\psi events. Explicit theoretical formulae for the partial wave analysis (PWA) of the J/\psi \to B^*\bar B +\bar B^* B with B^*\to B \gamma and \bar B^*\to \bar B\gamma within covariant L-S Scheme are provided.
