Figure 5
(Left) NRR time spectra measured at several grazing angles in the vicinity of the critical one for selected positions on the Fe60Al40 gradient sample (symbols are the experimental counts and lines are the fit). (Middle) The depth distribution of the 57Fe nuclei with selected types of hyperfine interaction and the corresponding resonant spectra for the normal direction of the radiation obtained by the fit. (Right) Overall resonant spectra at each depth calculated for the direction along the grazing-incidence synchrotron beam. |
