This paper shows how one can use potentials to build up a spin-zero model of the deuteron. The spin-zero model consists of a proton, and another proton plus an electron which combine in an electrically neutral particle which we refer to as the neutron. We treat all particles as spin-zero particles because we assume their magnetic moment is zero. As such, it may complement Paolo Di Sia’s model of the nucleus (2018), which we give due attention. In contrast to Di Sia, we think of neutrons – or the electron cloud that surrounds the proton inside – as electric dipoles. The model does so by interpretating Yukawa’s potential function as a dipole potential. Instead of predefining the range parameter a, we calculate it from the equilibrium condition (equal but opposite magnitudes of the Coulomb and nuclear forces). We find a very acceptable value of about 2.88 fm for a, and find an equally acceptable value for the distance between the positively charged center of the neutron and the center of the electron cloud which, in a deuteron nucleus, must shift it center of charge towards the proton so as to ensure stability – not unlike the sharing of valence electrons in chemical bonds.
