Theory of radioactivity
WebbTheory of Alpha Decay – Quantum Tunneling Alpha decay (or α-decay and alpha radioactivity) represents the disintegration of a parent nucleus to a daughter through the emission of the nucleus of a helium atom. This transition can be characterized as: As can be seen from the figure, the alpha particle is emitted in alpha decay. Webb14 dec. 2024 · An unstable fission fragment with the excess of neutrons undergoes β− decay, where the neutron is converted into a proton, an electron, and an electron antineutrino. A free neutron also undergo this type of decay.

Webb8 aug. 2024 · There are three main forms of radioactive emissions. The first is called an alpha particle ,which is symbolized by the Greek letter α. An alpha particle is composed of two protons and two neutrons, and so it is the same as a helium nucleus. (We often use He 2 4 to represent an alpha particle.) It has a 2+ charge.
