Lattice response to the radiation damage of molecular crystals: radiation-induced versus thermal expansivity.

ABSTRACT: The interaction of intense synchrotron radiation with molecular crystals frequently modifies the crystal structure by breaking bonds, producing fragments and, hence, inducing disorder. Here, a second-rank tensor of radiation-induced lattice strain is proposed to characterize the structural susceptibility to radiation. Quantitative estimates are derived using a linear response approximation from experimental data collected on three materials Hg(NO₃)₂(PPh₃)₂, Hg(CN)₂(PPh₃)₂ and BiPh₃ [PPh₃ = triphenylphosphine, P(C₆H₅)₃; Ph = phenyl, C₆H₅], and are compared with the corresponding thermal expansivities. The associated eigenvalues and eigenve
