Abstract
Using a pulsed-source neutron spectrometer we have measured the quasi-elastic incoherent dynamic structure factor of pure water in the temperature range 256-293 K. The high energy resolution and the wide energy transfer window allowed us to separate the translational diffusive motions from the relational ones. The translational dynamics has been analysed on the basis of a random-jump model that describes quite well the average behaviour of the quasi-elastic broadenings as a function of momentum transfer.Keywords
