| 摘 要： | A method for effectively generating long-lived Moessbauer photons and methods for proving the associated ;Moessbauer effects are reported. For the first time, we observed resonant propagation and resonant absorption of 40-keV Moessbauer photons emitted from ^103Rh through （γ, γ′） process excited by bremsstrahlung. This is a new efficient way to generate long-lived isomer （〉 1ms） for Moessbauer spectroscopy with sufficient brilliance. An abnormally large ratio of resonant absorption between horizontal and vertical directions indicates horizontal trapping- of Moessbauer photons and anisotropic Mbssbauer emission, which can be attributed to gravitational effect on the ^103Rh Moessbauer isomer with extremely narrow 10^-19eV linewidth.
