Antiparticle Lettering in Powerpoint: Jeans' Challenge

[Math Jeans]

I've got a challenge for you guys.

I'm doing a powerpoint presentation which involves written forms of particle decay, and I was wondering if there was a way to write a letter with a bar over the top in order to indicate an antiparticle without the use of images or shapes.

You can probably find what you want using the "Symbol..." command on the "Insert" menu (available only when the cursor is inside a text box).
