摘要：

The crystal structure of arsenic has been studied in a diamond anvil cell by energy dispersive x-ray diffraction with a synchrotron source to 122 GPa, where V/V0=0.513. The phase sequence on compression is: scAs(III)bcc. As(III) may have the -Np structure. The equilibrium transformation pressures, Pe, between sc/As (III) and As(III)/bcc are 4811 and 9714 GPa, respectively. There is no measurable volume discontinuity between the phases. The equation of state was measured and the BE2 parameters are in good agreement with literature values. © 1995 The American Physical Society.
