Yes, but I wonder if Ed knows of a version that does not release a positron?
Positron annihilation would have been seen by V&B, and one of their meters was designed for that. On the #2 spot on the list, this reaction is listed without the electron mentioned, but with the preface saying that any of these reactions could be screened, i.e. by the Heffner deflated electron. -----Original Message----- From: Jed Rothwell Ed Storms suggests: H-e-H --> D - Jed
