Lattice constants, crystallite sizes and strains of irradiated samples. (a) The lattice constants for as-prepared and sintered samples; (b) The crystallite sizes and lattice strains; (c) LDA+U calculated external pressure and Murnaghan’s empirical pressure (\(\Delta V/V=1-{e}^{-P/c}\))26; (d) The increase of LDA+U ground state energy upon pressure (polynomial fitting is given).
