Now that's the problem in a nutshell. The P-P process has never been observed, no once. Not in any experiment in the history of science. So you presume something that has nothing to do with reality. I think it was Hans Bethe who invented the process (or at least built a horse to ride on from its assumptions) and no one has taken him or anyone else to task on it. When one cannot differentiate the work product of a so-called scientist from that of a pathological liar then the proper conclusion is that there is no difference and that science which makes use of such work products has itself become pathological. P-P chain energys are observed and now the solar neutrino problem has been solved. PHYSICS NEWS UPDATE The American Institute of Physics Bulletin of Physics News Number 617 December 13, 2002 by Phillip F. Schewe, Ben Stein, and James Riordon PHYSICS STORIES OF 2002. The top two physics stories for the past 12 months were the total accounting of neutrinos from the sun by the Sudbury Neutrino Observatory (SNO), thus solving the solar neutrino problem (Update 586; www.aip.org/enews/physnews/2002/split/586-1.html); and the formation and detection of antihydrogen atoms at CERN (Updates 605 and 611, www.aip.org/enews/physnews/2002/split/605-1.html and www.aip.org/enews/physnews/2002/split/611-1.html). Other notable physics developments for the year include stopping and storing light in a solid (Update 571), the observation of phase-transition behavior in nuclei (572), publication of some unsent letters by Niels Bohr to Werner Heisenberg (576), interferometry with C-70 molecules (579), a dispute over "fusion" in sonoluminescence (579, 599), most precise tests of special relativity (571, 590), sharper maps of the cosmic microwave background (591), "droplet" of light (596), claims for element 118 retracted (597), verification of the notion that the second law of thermodynamics can be violated on small spacetime intervals (598), high precision measurements of CP violation in B meson decays and in the g-2 factor of the muon (600), scandal at Lucent (606), record high laboratory magnetic fields (614), polarization in the cosmic microwave background detected (606), 2002 Nobel prize for physics (608), noise can improve balance (612), and longest measured atomic lifetime (616). All the above Update items can be retrieved from our archive at www.aip.org/physnews/update. REACTOR ANTI-NEUTRINO DISAPPEARANCE, measured by a detector in Japan, supports the idea that neutrinos oscillate from one type to another and that they possess mass. Nuclear reactors produce several things: heat, electricity, spent fuel rods, and neutrinos. The neutrinos (or, to be more exact, electron anti-neutrinos) are a result of fission reactions inside the reactor core. But some of the electron antineutrinos, once they're underway and moving through the Earth, manifest one of the weirdest phenomena in all of physics, namely the ability to exist as a composite of several sub-species. That is, what we call a neutrino is really several (perhaps three) neutrinos in one. At any point along its trajectory the generic neutrino might (if you were to capture it just then) appear as an electron neutrino, but farther along it might look like a muon neutrino, in which case it would elude detectors tuned to detect only electron nu's. The Kamioka Liquid Scintillator Anti-Neutrino Detector (KamLAND) sets out to sample this odd mode of being. The apparatus, basically a huge reservoir of optically-active liquid viewed by numerous phototubes, looks for interactions in which an incoming nu strikes a proton, creating in their stead a trackable neutron-positron pair. KamLAND resides in an underground lab beneath Toyama, Japan. It is a sort of telescope peering not at galaxies in the sky; instead it stares through a block of terrestrial crust looking for the neutrino warmth cast off by a constellation of 69 reactors in Japan and Korea. Taking into account the laws of physics governing the reactions in the reactor cores, the known power ratings for the reactors, their aggregate reactor-detector distances, and the duration of the experiment (145 days), one would expect seeing 86 true events, whereas the actual number was 54. The researchers conclude that the disappearance of events is due to neutrino oscillation. This result is not merely a confirmation of oscillation research carried out with solar nu's at such detectors as Super Kamiokande in Japan and the Sudbury Neutrino Observatory (SNO) in Canada (see Update 586, http://www.aip.org/enews/physnews/2002/split/586-1.html). For one thing KamLAND studies anti-neutrinos rather than neutrinos. Furthermore, the production of neutrinos in a reactor is much closer at hand and better understood than is the case for the sun. The KamLAND finding also serves to narrow the theoretical explanation of the neutrino's split personality.
