Cross-section and analyzing-power data are presented for the C12(p,p′)C12 reaction at bombarding energies of 155 and 200 MeV. Comparisons are made with the systematics of data from other energies. Distorted-wave impulse-approximation calculations for the "pion-like" 1+, T=1 transition to the 15.11-MeV state are successful for q<280 MeV/c, but are substantially smaller than the data at larger momentum transfers. The implications of the data regarding precritical behavior associated with the pion-condensation threshold are discussed. NUCLEAR REACTIONS C12(p,p′), E=155 MeV, measured σ(E,θ); E=200 MeV, measured σ(E,θ), Ay(θ); θ=6-50°, Δθ=2-3°, Ex=11-17 MeV. DWIA analysis. Precritical phenomena near pion-condensation threshhold.
