| Abstract: | By using the partial wave method, we investigate the absorption of massless scalar wave from Schwarzschild black hole surrounded by the quintessence. We obtained the expression of absorption cross section 080402 Then we numerically carry out the absorption cross section and we find that the larger angular momentum quantum number l is, the smaller the corresponding maximum value of partial absorption cross section is, and that the total absorption cross section tends to geometric-optical limit σabshf≈ π bc2. We also find that higher value of ωq (state parameter of the quintessence) corresponds the higher value of absorption cross section σabs. |
