Abstract
By using the partial wave method, we investigate the absorption of a massless scalar wave from a Schwarzschild black hole surrounded by quintessence. We obtained the expression of absorption cross sectionThen we numerically carry out the absorption cross section and we find that the larger the angular momentum quantum number l is, the smaller the corresponding maximum value of the partial absorption cross section is, and that the total absorption cross section tends to the geometric-optical limit σhfabs ≈ πb2c. We also find that higher value of ωq (state parameter of quintessence) corresponds to the higher value of absorption cross section σabs.
