The proton proton (PP) fusion reaction is the most enigmatic nuclear reaction that you will ever run across. This reaction has concerned me a lot and still confuses me.
https://en.wikipedia.org/wi... Proton–proton chain reaction The PP reaction should not occur, but it is said to occur as the power source of the Sun as well as all the other stars because there is so much hydrogen involved in the energy cycle of the Sun. "In the Sun, deuterium-producing events are rare. Diprotons are the much more common result of proton–proton reactions within the star, and diprotons almost immediately decay back into two protons. Since the conversion of hydrogen to helium is slow, the complete conversion of the hydrogen in the core of the Sun is calculated to take more than 10^10 (ten billion) years." The PP reaction should be impossible to happen here on earth, but there is evidence that helium is being generated in all sorts of LENR systems. Why does LENR make PP fusion possible or possible very likely to occur? The reason for a vibrant PP reaction to occur in LENR is the huge increase in the likelihood of weak force reactions. LENR boosts both the strength and probability for the weak force to manifest by huge amounts. We have seen this sort of weak force amplification happen in the transmutation of Ni58 to Ni62 and Ni64. In the Luano test, all the natural nickel isotopes were converted into Ni62. Where did all those extra neutrons come from to transmute all the Ni58 to Ni62? LENR generates a massive increase in the strength of the weak force that converts all those protons into neutrons. The weak force is there to change protons into neutrons to balance out and stabilize nuclear reactions. The occurrence of PP fusion in SAFIRE is actually a LENR reaction. The chiral separation of particle spins into right and left handed helicity produces this massive increase in the weak-force. In SAFIRE, protons are forced together so forcefully that they form diprotons. Diprotons are unstable and normally, the protons in that pairing are forced apart by like charge repulsion. But instead, the hyper-strong weak force then transmutes these diprotons into deuterium. Now the deuterium is easily transmuted into Helium 3 when another proton merges with the newly created deuterium. Rather that taking 10 billion years for deuterium to form from diprotons, it takes instead picosecons in the LENR envirnment established by particle chirality.
