  1. Several isotropic moduli and velocities are shown on the right-hand side. The upper two rows are for Pbnm or Pv structure, while the lower two rows are for Cmcm or pPv structure. In each case, the first row gives the present experimental results with accuracy and the second row the theoretical results obtained by Tsuchiya and Tsuchiya17. The unit is ‘GPa’ except for velocities which have a unit of ‘m s−1’ in the last two columns. The numbers in parentheses correspond to fitting error in the least square analysis.
