Photoionization of bonding and antibonding-type atom-fullerene hybrid   states in Cd@C$_{60}$ vs Zn@C$_{60}$60
  Powerful hybridization of the Cd 4$d$ state with the $d$-angular momentum state of C$_{60}$ $\pi$ symmetry is found in the local density approximation (LDA) structure of Cd@C$_{60}$ ground state. The photoionization of the resulting symmetric and antisymmetric levels are computed using the time dependent LDA method to include electron correlations. Cross sections exhibit effects of the C$_{60}$ plasmonic motion coherently coupled to the diffraction-type cavity oscillations induced by local emissions from C$_{60}$. The Cd@C$_{60}$ results exhibit a substantial difference from our previous results for Zn@C$_{60}$.
