Color-suppressed decays of B mesons to final states with ψ(2S) mesons have been observed with the CLEO detector. The branching fractions for the decays B+ψ(2S)K+, B+ψ(2S)K*(892)+, B0ψ(2S)K0, and B0ψ(2S)K*(892)0 are measured to be (7.8±0.7±0.9)×10-4, (9.2±1.9±1.2)×10-4, (5.0±1.1±0.6)×10-4, and (7.6±1.1±1.0)×10-4, respectively, where the first uncertainty is statistical and the second is systematic. The first measurement of the longitudinal polarization fraction is extracted from the angular analysis of the Bψ(2S)K*(892) candidates: ΓL/Γ=0.45±0.11±0.04. Our measurements of the decays B0ψ(2S)K0 and B+ψ(2S)K*(892)+ are first observations.
