Abstract
ABSTRACTQuasielastic neutron scattering measurements of [Ni(NH3)6](N03)2 were made with two different resolutions of ca. 140 and 30 μeV. The following suggestions are analyzed:1. The NH3 rotational diffusion model is more adequate than NH3 120° jump model.2. Some NH3 groups slow down whereas some rotate rapidly.3. There exists an additional QNS component close to the phase II/phase III transition.
