Abstract: Alpha decay is proved to be one of the most puzzling because the α particles appears at energies which, classically, should be inaccessible. An α particle, incident on a heavy nucleus like uranium, experiences a Coulomb barrier in excess of more than 20MeV. Yet α particles are emitted from uranium with energies of less than 5MeV, apparently violating energy conservation in the vicinity of the barrier. The aim of this paper was to verify whether the emission of α- particle through a coulomb barrier actually contradicts with the principle of conservation of energy. However, the calculation of the degree of transmission probability or penetrative factor of α- particle through the barrier height shows that the process of α- decay does not actually violate the principle of conservation of energy in the vicinity of a Coulomb barrier.
