Query: Scattering of Long-Wavelength Gravitational Waves   We consider the scattering of a low-frequency gravitational wave by a massive
compact body in vacuum. We apply partial-wave methods to compute amplitudes for
the helicity-conserving and helicity-reversing contributions to the cross
section, accurate to first order in $M\omega$. Contrary to previous claims, we
find that the partial-wave cross section agrees with the cross section derived
via perturbation-theory methods.
