FOLLOWING the results of scattering experiments, the hypothesis is now generally favoured1 that the interaction forces in nuclei do not depend on the charge of the particles concerned. Then the general interaction potential for two particles 1 and 2, either of which may be a proton or a neutron, can be expressed as: Here σi is the spin vector of the particle i and τi the formally analogous "isotopic spin vector"2 ; τiz has the value + 1, if i is a proton, and mdash;1, if i ia a neutron ; W, B, H and M are four constants. From (1) we obtain (W + B + H + M)J(r) as the potential in the ground state of the deuteron. If J(r) is correspondingly normalized we may put:
