在广义相对论的后闵可夫斯基方法中，我们证明了在两个粒子的大碰撞参数散射过程中，（经典）点质量通过涉及高能的G^3阶的额外贡献修改了保守散射角。（或无质量）对数发散相反的符号包含在第三个后闵可夫斯基结果的伯尔尼等人。[物理评论Lett. {f 122}，201603（2019）]。得到的辐射-反应-校正的（经典）散射角的高能极限是有限的，并且被发现与从Amati、Ciafaloni和Veneziano [Nucl. Phys. B {[347]，550（1990）]。
Working within the post-Minkowskian approach to General Relativity, we prove that the radiation-reaction to the emission of gravitational waves during the large-impact-parameter scattering of two (classical) point masses modifies the conservative scattering angle by an additional contribution of order $G^3$ which involves a high-energy (or massless) logarithmic divergence of opposite sign to the one contained in the third-post-Minkowskian result of Bern et al. [Phys. Rev. Lett. {f 122}, 201603 (2019)]. The high-energy limit of the resulting radiation-reaction-corrected (classical) scattering angle is finite, and is found to agree with the one following from the (quantum) eikonal-phase result of Amati, Ciafaloni and Veneziano [ Nucl. Phys. B {f 347}, 550 (1990)].
