Abstract: High-pressure, angular-dispersive, X-ray diffraction measurements have been performed on ¿115¿ superconductors CeMIn5 and PuMGa5 for M = Co and Rh. The principal results are the pressuredependencies of the tetragonal lattice parameters, c/a, in each system, which are presented for the purpose of understanding the role that this parameter plays in controlling the value of the superconducting temperature, Tc. In none of the systems investigated does c/a scale linearly with the value of Tc under pressure, suggesting that it is not the main parameter to control Tc. Values of bulk modulus determined from these measurements are also presented.
