Β particles
beta particles (beta), also translated beta or shellfish particles, when the radioactive material beta decay, the release of high-energy electrons, the speed of up to 90% of the speed of light. In the process of beta decay, the radioactive nuclei are transformed into another by electrons and neutrinos, and the electrons in the product are called beta particles. In the positive β decay, a proton in the nucleus is transformed into a neutron, and a positive electron is released. In the "negative β decay", a neutron in the nucleus is transformed into a proton, while releasing an electron, that is, the beta particle Will release anti-micro-neutrons. Since the mass of the electrons is much lighter than the proton, the neutrons are much lighter, and when the β particles pass through an electric field, if it is negative electrons, the path is distorted in the direction of the positive pole. In the case of a magnetic field, if the direction of the magnetic field is from the inside to the outside, its particles will be twisted in counterclockwise direction, the path is curved, this distortion can be described using the right hand of the amperage: the thumb represents the direction of the magnetic field, the other four fingers on behalf of the negative Distort the path. ...
