Inelastic neutron scattering (INS) measurements were performed on the rare earth dimer compounds Cs3Er2X9 (X=Cl,Br). The crystalline electric field (CEF) parameters were determined. The lack of any exchange splitting associated with the CEF transitions can be explained by the large single-ion anisotropy for Er. Specific heat and susceptibility data support the picture of an almost pure Ising system, which splits the lowest CEF state in the Cheap Ugg Australia Uk
presence of the dimer interaction into a non-magnetic ground-state doublet and a magnetic excited doublet without any allowed transition between these two dimer states.
A simple model of the taxi industry Ugg Stockists Uk Kids
suggests that deregulation of fares and entry may not be optimal. the conditions of competition do not hold in the industry, even approximately. A model of search, where drivers and riders search for each other, is presented for the cruising-taxi market. This indicates that equilibrium of a deregulated industry does not exist. Price regulation is essential, and entry regulation may be useful. In addition, viewing the medallion as a bond for appropriate performance provides another possible rationale for regulation.
