Intro to Quantum Mechanics II
Alpha decay is a type of radioactive decay in which an unstable atomic nucleus emits an alpha particle, consisting of two protons and two neutrons, effectively transforming into a different element. This process occurs because the original nucleus seeks stability by reducing its mass and atomic number, leading to the emission of the alpha particle. The phenomenon is closely related to tunneling and barrier penetration, as the alpha particle must overcome an energy barrier to escape the nucleus.
congrats on reading the definition of Alpha Decay. now let's actually learn it.
