  Using a sample of 88.8 10**6 BBbar events collected with the BaBar detector
at the PEP-II storage rings at the Stanford Linear Accelerator Center, we
measure the branching fractions of seven color-suppressed B-meson decays:
  BF(B0bar to D0 pi0)=(2.9 +/- 0.2(stat.)+/- 0.3(syst.))*10**-4,
  BF(B0bar to D*0 pi0)=(2.9 +/- 0.4(stat.)+/- 0.5(syst.))*10**-4,
  BF(B0bar to D0 eta)=(2.5 +/- 0.2(stat.)+/- 0.3(syst.))*10**-4,
  BF(B0bar to D*0 eta)=(2.6 +/- 0.4(stat.)+/- 0.4(syst.))*10**-4,
  BF(B0bar to D0 omega)=(3.0 +/- 0.3(stat.)+/- 0.4(syst.))*10**-4,
  BF(B0bar to D*0 omega)=(4.2 +/- 0.7(stat.)+/- 0.9(syst.))*10**-4, and
BF(B0bar to D0 eta_prime)=(1.7 +/- 0.4(stat.)+/- 0.2(syst.))*10**-4.
  We set the 90 % confidence-level upper limit:
  BF(B0bar to D*0 eta_prime) < 2.6*10**-4.
  The channels B0bar to D*0 eta, D*0 omega, and D0 eta_prime are seen with more
than five-sigma statistical significance. All of these branching fractions are
significantly larger than theoretical expectations based on the ``naive''
factorization model.
