  We study the semiclassical fluctuation problem around bounce solutions for a
self-interacting scalar field in curved space. As in flat space, the
fluctuation problem separates into partial waves labeled by an integer l, and
we determine the large l behavior of the fluctuation determinants, a quantity
needed to define a finite fluctuation prefactor. We also show that while the
Coleman-De Luccia bounce solution has a single negative mode in the l=0 sector,
the oscillating bounce solutions also have negative modes in partial waves
higher than the s-wave, further evidence that they are not directly related to
quantum tunneling.
