Abstract

A neutron powder diffraction study was performed to determine the sites occupied by hydrogen in the structure of DHMS phase G, which is stable at the pressure-temperature conditions of the transition zone and lower mantle. The diffraction data from small samples (about 3 mg) were collected by using a highly sensitive imaging plate detector at the BIX-3 beamline at JRR-3M nuclear plant in JAERI Tokai Laboratory, Japan. The present neutron diffraction data reveal that hydrogen (and deuterium) is located in the 6k site of Wykoff letter in the MO₆ layer of the phase G structure with the space group P31m. The bond lengths of O-H and O-D are 1.1(4) and 0.8(3) A, respectively. This result is consistent with previous Raman spectroscopic studies of this phase.
