EQUATION-OF-STATE DATA FOR CSCL-TYPE ALKALI-HALIDES

Energy-dispersive x-ray diffraction (EDXD), with synchrotron radiation and diamond anvil cells (DAC), is used with different pressure sensor s to determine the lattice parameters and equations of state (EOS) at room temperature, and pressures up to typically 40 GPa, for KBr, KI, R bCI, RbBr, RbI, CsCl, and CsBr. A comparison with previous literature data obtained by various techniques, and for different ranges of press ure indicates that all of the data fit to a recently proposed 'simple' first-order EOS form.
