WebDec 14, 2024 · Alpha decay (or α-decay and also 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, alpha particle is emitted in alpha decay. Alpha particles are energetic nuclei of helium. WebAlpha decay of a nucleus can occur despite the presence of the potential repulsion barrier. This penetration of the potential barrier is often called tunnelling.
