# Bold and italic in subsection

In the following documentclass

\documentclass[prb,twocolumn,showpacs]{revtex4}


how to have italic and bold in a subsection title? The italic command removes the boldness when inside a subsection, so I tried the following :

\subsection{Short-range {\bf {\it vs}} long-range scattering}


It does not work. Any idea how to solve this? Maybe the documentclass has nothing to do with it, I did not check it.

For the record, the Documentation on Obsolete commands and packages warns against continuing to use "\it" and "\bf". – frabjous Jan 18 '11 at 16:49

This has nothing to do with the documentclass, but with font selection. \it selects non-bold italics, and \bf selects non-italic bold. You should use

\textbf{\textit{vs}}


Try doing \textit{\textbf{vs}} instead. That should work.
Using \secit{vs} would solve the problem. This is how I worked it out for my subsection when I needed both bold and italic.
Welcome to TeX.sx! A tip: You can use backticks  to mark your inline code as I did in my edit. – doncherry Jan 6 '13 at 7:04
How is \secit defined? revtex4` does not include it. – Werner Jan 6 '13 at 7:04
