Kinds of 4N nucleus :

• alpha-particle (4 facts) - The nucleus of a ⁴He atom, consisting of two protons and two neutrons. Mass of α-particle 4.00260 amu., Nucleus formed by the α-process (q.v.) (see even-even nuclei)., Particle first discovered in radioactive α decay, and later identified as helium nuclei (two protons and two neutrons bound together).
