We compute the two closed string graviton - two open string scalar scatteringamplitude on the disc to show that there is no second-derivative curvature -scalar coupling term R X^2 in the low-energy effective action of a D-brane incurved space in type II superstring theory.Comment: 15 pages, 1 figure, LaTex JHEP style; v2: reference added, typos corrected; v3: section 2 rewritten due to an error in gauge fixing, appendix added, conclusions unchange
