Nuclear models

It is known since one century that nuclear energy is of the order of one million times more concentrated, in the same mass, than chemical energy.The radius of the atomic nucleus is, indeed, of the order of one million times smaller than that of a molecule. This is because the chemical and nuclear binding energies are of the same electric nature : they obey both to the Coulomb's laws, in 1/r where r is the radius of either a nucleus or a molecule. No need of a mysterious "strong force". According to Einstein, the energy of an... [Lire la suite]
