Development Of ~(151)eu Time-domain Interferometry And Its Application For The Study Of Slow Dynamics In Ionic Liquids

摘要

Time-domain interferometry (TDI) employing ~(151)Eu nuclear resonant scattering was developed for the study of slow dynamics. We measured the relaxation times of the density correlation in super-cooled ionic liquid 1 -butyl-3-methylimidazolium iodide (Bmiml) by the developed TDI. We found that the temperature dependence of the relaxation times follows the Vogel-Fulcher-Tammann law and observed fragile behavior of Bmiml. Furthermore, we discussed the potential of TDI for the study of slow dynamics.
