Abstract
ABSTRACT The quasi-hydrostatic compression of cesium chloride and cesium bromide has been measured with X-ray diffraction up to 141 GPa at 300 K. A cubic to orthorhombic transition, with a ≥10% distortion of lattice parameters, is evidenced in CsBr around 60 GPa. A smaller distortion (∼1.5%) appears in CsCl at the same pressure, followed by a likely transition to a lower symmetry phase which starts at 134 GPa. P−V compression curves yield equation of state parameters in line with those of other B2 alkali halides.
期刊介绍：
High Pressure Research is the leading journal for research in high pressure science and technology. The journal publishes original full-length papers and short research reports of new developments, as well as timely review articles. It provides an important forum for the presentation of experimental and theoretical advances in high pressure science in subjects such as:
condensed matter physics and chemistry
geophysics and planetary physics
synthesis of new materials
chemical kinetics under high pressure
industrial applications
shockwaves in condensed matter
instrumentation and techniques
the application of pressure to food / biomaterials
Theoretical papers of exceptionally high quality are also accepted.
