# On the construction of atomic kernels

Can anybody point me to an English translation of Heisenberg’s three part paper Über den Bau der Atomkerne?

Failing that, can you point me to a non-paywalled German version of part III? I have parts I and II in German, but not part III.

Thanks in advance. I shall award a 100-point bounty to the answer that best assists.

Edit 14/01/2017: and if nobody can answer that, here's a bonus question. But you have to answer both parts to qualify for the bounty: If the nuclear force is charge-independent then a) how come there are no diprotons, and b) what's responsible for the repulsion in the deuteron?

• I suppose that with question (a) you mean that the answer should be "irrespective of electromagnetic interactions"? In any case, note that charge symmetry doesn't mean that the force doesn't depend on total isospin. The deuteron has isospin $I=0$, while a di-proton has $I=1$. – pppqqq Jan 14 '17 at 17:00
• @pppqqq : no, I didn't mean irrespective of electromagnetic interactions. The nuclear force is supposed to be stronger than the electromagnetic force: "at short range the attractive nuclear force overcomes the repulsive electromagnetic force". I found the 1936 paper that is said to have established charge independence to be rather unconvincing myself. See Theory of Scattering of Protons by Protons by Gregory Breit et al. – John Duffield Jan 14 '17 at 17:13
• Your "bonus questions" are different enough from your reference request that they might stand on their own rather than fit here as an edit. – rob Jan 15 '17 at 1:55
