Abstract
The total reflection of the recoilless 8.4 keVγ-radiation of Tm169 was observed at various glancing angles between 3 and 7 milliradians on surfaces of Tm metal and Tm2O3 produced by vacuum evaporation. The Mössbauer velocity spectra of the reflected intensity show a typical dispersion pattern due to interference between electronic and nuclear resonant scattering, which can be understood quantitatively, thus permitting the determination of the nuclear scattering amplitude. From this the total conversion coefficient of the 8.4 keV transition was derived to be α=220±50.
