However, the impact of Ly$\\alpha$ radiation force on this issue remains poorly understood. We investigate the propagation of the Ly$\\alpha$ photons and evaluate the Ly$\\alpha$ radiation force within a spherically symmetric accreting HI gas onto the central black hole. We solve the radiation transfer equation, incorporating the destruction processes of Ly$\\alpha$ photons through two-photon decay and collisional de-excitation.
