Gravitational Radiation from a Particle Falling Radially into a Schwarzschild Black Hole

We have computed the spectrum and energy of gravitational radiation from a "point test particle" of mass m falling radially into a Schwarzschild black hole of mass M. The total energy radiated is about 0. 0104mc^2 (mM), 4 to 6 times larger than previous estimates; the energy is distributed among multipoles according to the empirical law E₂₋-₏₎₋₄ (0. 44m^{2c^2}M) e^-2l; and the total spectrum peaks at an angular frequency =0. 32c^{3}GM.
