Don't need to. He Who Shall Not Be Named kindly did so for me and was even kind enough to cc me a copy. Just a question, but you commented on positive electrons and said they don't exist, but weren't they discovered in the early 1930s? The more correct name for this component of the electron is the positron and you can read about its discovery at http://focus.aps.org/story/v17/st5 Here is part of the definition found at Wikipedia: The positron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1, a spin of 1/2, and the same mass as an electron. When a low-energy positron collides with a low-energy electron, undergoing an annihilation event, their mass is converted into the kinetic energy of two gamma ray photons (see electron-positron annihilation). An electron has a negative charge, a positron has a positive charge. They are different particles. Back in the day (middle of 20th century) the term positive electron may have been correct. However, since the early 90s at least (when I went through undergrad and grad school) they have been called positrons. I should also point out that, being an antimatter particle, they have *extremely* short lifespans when not contained in a vacuum. By short I am talking millionth of a second. -- Marcel and Moogli http://mudbunny.blogspot.com/ |

And I shoudl also mention that when positrons and electrons meet, they do so destructively (think Star Trek and Anti-matter containment) with the release of gamma radiation. The stuff that they use in cancer treatments. -- Marcel and Moogli http://mudbunny.blogspot.com/ |
