WebOften overlooked for alpha particles is the recoil-nucleus of the alpha emitter, which has significant ionization energy of roughly 5% of the alpha particle, but because of its high electric charge and large mass, has an ultra-short range of only a few Angstroms. WebThere are no external forces acting on the system. Thus the total energy (K.E.+P.E.) of the system is constant. 2. Initially the alpha particles are at a very large distance from the nucleus. Rearranging: For an alpha particle: m (mass) = 6.644 24 × 10−27 kg = 3.7273 × 109 eV/c2 q1 (for helium) = 2 × 1.6 × 10−19 C = 3.2 × 10−19 C
