The principles of gravitational gamma-resonance spectrometry are described in comparison with classical methods. The scheme of the ITEP experimental setup for gravitational gamma-resonance spectrometry of long-lived isomers and the experimental results are presented. The expected results for the new 103mRh long-lived gamma-resonance spectrometer are discussed. The prospects of a fundamentally new technology for using the gravitational field to study gamma resonances of long-lived isomers and the use of ultra-narrow gamma resonances for accurate gravitational measurements are considered.

Key words: gravitational gamma-resonance spectrometry, experimental seput, expected result.
