How do I typeset harpoon arrows that look like this in LaTeX?
I've tried the harpoon package's \overrightharpoon feature, but its arrowhead is too big/prominent... I'm hoping for something that looks more normal, like in the screenshot above.
How do I do this?
You could use \rightharpoonup and \overset (which needs the amsmath package). Because
\overset{\rightharpoonup} is quite long, I would define a newcommand, like so:
\newcommand{\harpoon}{\overset{\rightharpoonup}}
Only the space above seems a little bit unpleasant. But it works just fine.
Code
\documentclass{article}
\usepackage{amsmath}
\newcommand{\harpoon}{\overset{\rightharpoonup}}
\begin{document}
\[
\Delta \overset{\rightharpoonup} L =
\harpoon L_2 - \harpoon L_1 = \harpoon 0
\]
\end{document}
Result
