  The bounce solutions of self-interacting scalar fields coupled to gravity are
studied using a semi-classical approach. We found that bounce solutions have a
maximum required barrier curvature, in addition to the known minimum required
barrier curvature. In particular, as the maximum barrier curvature is
approached, the scale factor of the well-known Colemen-De Luccia (CDL) bounce
solutions become divergent. Unlike the CDL or its more general oscillating
bounce counterparts, this cannot be considered as a subset of the Hawking-Turok
solution.
