Take your pick. If you need information on the isotopes here are some good websites:
en.wikipedia.org/wiki/Isotopes_of_carbon‎
http://www.webelements.com/carbon/isotopes.html
education.jlab.org/itselemental/iso006.html‎
ethomas.web.wesleyan.edu/ees123/carboniso.htm
www.esrl.noaa.gov/gmd/education/isotopes/‎
invsee.asu.edu/Modules/carbon/isotope.htm‎
www.chem.ox.ac.uk/vrchemistry/Conservation/page34.htm‎ (it's somewhere in there)
The rest are in here: https://www.google.com/#q=isotopes+carbon&start=10

By the way, shouldn't this be in Chemistry, what with the isotopes and all?
Just saying.
I'll let it slide, though. :p
