<dt>Description</dt>
<dd>We evaluate both the vacuum decay rate at zero temperature and the finite temperature nucleation rate for the &lt;math&gt;\left(\frac{\lambda}{4!}\phi^4+\frac{\sigma}{6!}\phi^6\right)_{3D}\,\!&lt;/math&gt; model. Using the thin-wall approximation, we obtain the bounce solution for the model and we were also able to give the approximate eigenvalue equations for the bounce.</dd>
