Ru concentration dependence of Raman spectra in Pr(Os₁₋_xRu_x)₄Sb₁₂ was measured at low temperature, where phonon peaks due to Sb vibrations and the transition peaks between crystal electric field (CEF) levels have been observed. The CEF energy levels and parameters were determined for each x. The excitation energy between the ground and the first excited states increases from 0.69 to 5.74 meV, as x increases from 0 to 1. A discontinuity in the CEF energies and parameters has been observed at x ∼0.6, where superconducting transition temperature T_c is the minimum. This discontinuity suggests an anti-crossing of the energy between the CEF and Pr rattling mode.
