When 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.
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.
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.
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.
He found that e/m for a beta particle is the same as for Thomson’s electron, and therefore suggested that the beta particle is in fact an electron.
Helium-6 decays by emitting a beta particle and has a half-life of 0.8 second.
