After reading this article you will learn about the properties of α, β and γ particles. Properties of Alpha (α) Particles: The alpha particles are doubly positively charged helium atoms i.e. the alpha rays consist of particles carrying two units of positive charges and having a mass of 4 units. It gives helium spectrum. The energies of α-particles are quite [...]
