We have studied the color-suppressed hadronic decays of neutral B mesons into the final states D(*)0π0. Using 9.67×106 BB̅ pairs collected with the CLEO detector, we observe the decays B̅ 0D0π0 and B̅ 0D*0π0 with the branching fractions B(B̅ 0D0π0) = (2.74-0.32+0.36±0.55)×10-4 and B(B̅ 0D*0π0) = (2.20-0.52+0.59±0.79)×10-4. The first error is statistical and the second systematic. The statistical significance of the D0π0 signal is 12.1σ ( 5.9σ for D*0π0). Utilizing the B̅ 0D(*)0π0 branching fractions we determine the strong phases δI,D(*) between isospin 1/2 and 3/2 amplitudes in the Dπ and D*π final states to be cosδI,D = 0.89±0.08 and cosδI,D* = 0.89±0.08, respectively.
