The symbol β − represents an electron emitted in nuclear beta decay. Cobalt-60 is a nuclide that β − decays in the following manner: 60 Co → 60 Ni + β − + neutrino. 2014-12-04 · There are two types of beta decay, known as beta minus and beta plus.In Beta minus (β−) decay a neutron transforms into a proton and an electron. 25 25 - Na ---> Mg + e + E. 11 12. In Beta plus (β+) decay a proton transforms into a neutron and a positron. 25 25 + Na ---> Ne + e + E In nuclear physics, beta decay is a type of particle decay in which beta radiation is emitted . It owes its name to the classification made by Emest Rutherford in 1899 of the radioactive emissions in alpha and beta, according to the capacity of penetration in the objects and the capacity of ionization.

Favorite Answer. Beta+ decay involves a proton converting to a neutron .. with the β+ (positron) carrying away the + charge. This results in a new In nuclear physics, beta decay is a type of radioactive decay in which a beta particle is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide. For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or, conversely a proton is converted into a neutron by the emission of a positron with a neutrino in so-called positron emission.

β+ - a positron - the antiparticle of the electron (same mass, opposite charge); νe - a neutrino; Electron capture can be viewed as the equivalent process to positron decay, since both processes result in the same nuclear transmutation - the formation of 22 10Ne.
