Noun
a high-speed electron or positron emitted in the decay of a radioactive isotope
Source: WordNetWhen I was 16 years old, I assembled a 2.3 million electron volt beta particle accelerator. I went to Westinghouse, I got 400 pounds of translator steel, 22 miles of copper wire, and I assembled a 6-kilowatt, 2.3 million electron accelerator in the garage. Michio Kaku
In electron and positron emission by beta decay the photon's energy comes from the electron- nucleon pair, with the spectrum of the bremsstrahlung decreasing continuously with increasing energy of the beta particle. Source: Internet
He found that m/e for a beta particle is the same as for Thomson's electron, and therefore suggested that the beta particle is in fact an electron. Source: Internet
The beta particle is moving faster than 0.75 c, but not faster than c. and thus generates blue Cherenkov radiation when it passes through water. Source: Internet
