The microscopic slow dynamics in various samples has been studied by a time-domain interferometry (TDI) method using nuclear resonant scattering (NRS) of synchrotron radiation and an improvement of the efficiency of TDI is highly desired. To realize it, we developed the TDI method using α-Fe foils with multi-line Mössbauer spectra as nuclear absorbers. Compared to the conventional TDI method using single-line Mössbauer absorbers, the reduction of the measuring time is expected by a simulation study. The simulation study shows a comparatively large change on the multi-line TDI time spectra by the diffusion in a sample and indicates much improvement of the efficiency. We obtained time spectra of the multi-line TDI and the obtained quasi-elastic broadening values of NRS energy width obtained by fitting the time spectra were confirmed to be close to the values obtained by the conventional TDI and estimated standard deviations by the multi-line TDI were comparatively small as expected by the simulation study.
