text: Unfortunately under the influence of the qualitative approaches of the so-called Pauli principle of two spinning electrons of opposite spin (1925), Heisenberg in 1932 for the explanation of the simple proton-neutron system proposed a fallacious isospin T since the parallel spin (S=1) of deuteron is forbidden by the “exclusion principle” characterizing the coupling of two electrons with antiparallel spin (S=0).
