Future JPL Space Engineer Posted October 15, 2014 Share Posted October 15, 2014 Hi scientists, I'm researching about positrons and related particles, I studied that the Beta Plus Decay produces positron like this: Hit Energy on Proton -> Produces Positron and Neutrino. Is that correct? Link to comment Share on other sites More sharing options...
swansont Posted October 15, 2014 Share Posted October 15, 2014 Hi scientists, I'm researching about positrons and related particles, I studied that the Beta Plus Decay produces positron like this: Hit Energy on Proton -> Produces Positron and Neutrino. Is that correct? Nothing hits the proton; the reaction is spontaneous, so it happens on its own. The proton becomes a neutron, and a positron and neutrino are also produced, which are ejected from the nucleus the proton was in; they carry away most of the energy released in the reaction. A proton by itself is stable and can't undergo such a decay. It has to be in a nucleus, and one in which there are enough protons that turning into a neutron puts it into a lower energy state (conceptually like something falling off a table gets to a lower energy state by going to the floor. It never spontaneously falls up) 1 Link to comment Share on other sites More sharing options...
