  We study quantum radiation emitted during the collapse of a quantized,
gravitating, spherical domain wall. The amount of radiation emitted during
collapse now depends on the wavefunction of the collapsing wall and the
background spacetime. If the wavefunction is initially in the form of a sharp
wavepacket, the expectation value of the particle occupation number is
determined as a function of time and frequency. The results are in good
agreement with our earlier semiclassical analysis and show that the quantum
radiation is non-thermal and evaporation accompanies gravitational collapse.
