Abstract
The low-temperature tunnel splittings of reorienting NH4+ ions in tetrahedral surroundings have been measured in (NH4)2PtCl6 and (NH4)2ReCl6 with neutron inelastic backscattering and in (NH4)2TeCl6 with nuclear magnetic resonance and field cycling. The tunnel splittings in these and other ammonium hexachlorides depend exponentially on the lattice dimensions.Keywords
