| contents | This paper studies scalar field perturbations coupled with Einstein tensors of non-exchange black holes. We use the polarization method to calculate graybody factors and absorption cross-sections selected by different parameters, and verify the latest correspondence between graybody factors and quasi-normal states. The results show that the larger the value of the non-exchange parameter $θ$ and the coupling constant $η$ introduced into the model, the smaller the absorption cross-section. Furthermore, we found that this correspondence is accurate for non-commutative black holes at the $1$ limit of large angular momentum quantum numbers. |
