The Breit-Pauli R-matrix method with 31 fine-structure levels is used to calculate elastic- and inelastic-scattering amplitudes between magnetic sublevels for He-like Cu ions by electron impact for x-ray polarization spectroscopy of ultrahigh-intensity laser-produced plasma. The collision strengths for inelastic scattering that produce aligned states are obtained for transitions from the ground state to the fine-structure levels of all the excited states of the 1s2l (l=0,1) and 1s3l (l=0,1,2) configurations. The collision strengths for elastic scattering that destroy the alignment of excited states are also obtained for transitions between magnetic sublevels of the 1s2p {sup 1}P{sub 1} states. The collision strengths including resonance structures are used for population alignment analysis. We find that resonances in the elastic scattering are significant for representing the relaxation effects of the alignment of excited states for the population alignment analysis.
