Crash Posted October 29, 2005 Share Posted October 29, 2005 Not sure if this is chem or physics but i came upon it in a chem book so here it is, Is electron capture and positron emission the same thing? like what are they and how do they differ? also what is a negatron? Cheers Link to comment Share on other sites More sharing options...
BigMoosie Posted October 29, 2005 Share Posted October 29, 2005 Positron emission is when a proton decays into a neutron and emits a positron and a neutrino. Electron capture is the same thing but instead of emitting a postron it absorbes an electron from one of its shells. They are similar in that they both decrease the element number by 1 but are distinct, electron capture occurs instead of positron emission when the nucleus has less energy. Thats about all I know about it. A negatron is another name for electron that failed to gain popularity. Link to comment Share on other sites More sharing options...
