Fig. 3From: Sound velocities of bridgmanite from density of states determined by nuclear inelastic scattering and first-principles calculationsInfluence of pressure on SL18 bridgmanite. a Selected NIS spectra. b Selected pDOS (upper) and reduced pDOS (lower). The SL18 pyroxene starting material was transformed to bridgmanite by laser heating in the DAC, and data were collected during three different beamtime experiments: #1—17, 36, 62, and 75 GPa; #2—50 GPa (not shown); and #3—65 GPaBack to article page
