Evidence from the paper
Table 1, 300 K Experimental column: V = 18.66 A^3 [Mao and Bell, 1979]; K_T = 160.5 GPa [Sumino et al., 1983]; K_T' = 4.22 [Chang and Barsch, 1969]. Text: 'about 11% higher than the experimental value of 160.5 GPa' and 'Our value is 4.15 compared to the experimental value of 4.22'.
