Why this differs from similar rows?
Table VI 'PIB Model' column, a theoretical potential-induced-breathing electron-gas calculation attributed to Ref. 2 (Cohen 1987); sibling row is experimental data.

note
Table header prints volume unit as 'Å'; almost certainly Å3 per unit cell. PIB results attributed to Ref. 2 (Cohen 1987).
