Bounce corrections to gravitational lensing, quasinormal spectral stability, and gray-body factors of Reissner-Nordström black holes

Gravitational lensing in the weak field limit, quasinormal spectra, and gray-body factors are investigated Reissner-Nordstr\"om spacetime corrected by bounce parameters. Using Gauss-Bonnet theorem, we analyze effects of corrections to gravitational deflection angle find that divergence can be suppressed a correction spacetime. We also notice plays same role as Morse potential angle. Moreover, derive perturbation equations with spin-dependent effective potentials discuss spectral stability. observe spectra have behavior large parameters for different multiple numbers they decrease significantly if parameter is much bigger than charge. further study transmission probability particles scattered reveal introduced into increases fields.
