Gravitational wave detection has been a very active field after the pioneering work of Weber [l]. A gravitational wave produces tiny relative displacements between various parts of a detector. Currently, gravitational wave detection efforts involve three distinct types of detectors: Doppler tracking of spacecraft, laser interferometers, and Weber-type resonant bars . These detectors have achieved a burst sensitivity capable of detecting gravitational waves with an amplitude of h = 3 x 10-16 at frequencies N 30 to 104 Hz. A detector for gravitational waves is proposed using the Mossbauer effect  in long lifetime nuclear isomers. This new type of detector can achieve a sensitivity of h = 10-16 or better depending on the nuclear isomer used. A nuclear isomer is an excited state of nuclei with a very long lifetime.
