Subject:  postrons







I read a brief article in the weekly Scientific American weekly e-mail

newsletter about scanning positron microscope (SPM).  The microscope uses an

isotope of sodium as its positron source.  Does anyone know what isotope it is

and the decay pathway that allows the the release of a positron?  I searched the

web and came up with zero.



Enjoy and thanks in advance - Tom
