Query: On Gravitational Radiation by a Quantum Bound System   A method based on the path integral approach is engaged to consider the
gravitational emission from a quantum mechanical bound system in a locally
inertial frame. In such a frame, interaction between the electromagnetic (bound
potential) and gravitational fields can be neglected resulting in the less
mathematical complexity. The final outcome is in agreement with the previous
result for the radiation intensity of emitted gravitons due to decay of bound
states in TT gauge.
