Math & Science ⇒ Exponent Sits Above Overbrace

[StarKid]

The fraction gamma/beta is showing up on top of the overbrace instead of off to the right. Also, is there a way to make the overbrace smaller?

MWE:

Code: Select all

\documentclass[12pt]{article}
\begin{document}

\[ h(r)=\left[\frac{\widetilde{S}(r)\overbrace{h(r)}^{\gamma/ \beta}}{L_{t} (r)}+\frac{(\alpha K)^{\gamma}}{L_{t} (r)(\rho_{t}+\delta+\delta g-g)} \right]^{\frac{\beta}{\beta+\gamma}} \]

\end{document}

Ok, I fixed the exponent positioning by adding braces around \overbrace and putting the exponent outside the braces:

Code: Select all

\[ h(r)=\left[\frac{\widetilde{S}(r){\overbrace{h(r)}}^{\gamma/\beta}}{L_{t} (r)}+\frac{(\alpha K)^{\gamma}}{L_{t} (r)(\rho_{t}+\delta+\delta g-g)} \right]^{\frac{\beta}{\beta+\gamma}} \]

but my overbrace is still way too large in certain cases, for example

Code: Select all

$\overbrace{f}(r)$
