[MiKTeX] math expression in \section

[Marcel S. <mar...@gm...>]

Hi,
I'd like to write f.e.

\section{Free Particle, $V(x) = 0$}

The value of \section is printed in the TOC and at the beginning of
the respective section. However, at the beginning of the Free
Particle-section the text in $$ isn't bold (what is not really nice).
If I use

\section{Free Particle, $\mathbf{V(x) = 0}$}

the text in $$ is also bold in the TOC, what isn't really nice, too.

What do I have to do in order to the text in $$ being printed nicely,
i.e. not-bold in the TOC and bold at the beginning of the section?

TIA !
Marcel
