Ezer, D., and A.G.W. Cameron, 1972: Effects of sudden mixing in the solar core on solar neutrinos and ice ages. Nat. Phys. Sci., 240, no. 104, 180-182, doi:10.1038/physci240180a0.
A continuous mixing throughout much of the solar interior might maintain a large abundance of hydrogen at the centre of the Sun, thus lowering the temperature relative to an unmixed model, and lowering the 8B neutrino flux by a factor 4 or so. Although this suggestion is unconventional, and some aspects of it are not very appealing in terms of present stellar evolution theory, once again the solar neutrino problem is facing a crisis. Davis and his co-workers reported at the Solar Neutrino Conference in San Clemente and Irvine, California, in February 1972, a new upper limit of the solar neutrino fluxes equivalent to 1 s.n.u. (10-36 interactions per second per 37 Cl target atom). Solar model calculations, allowing for the recent reduction of the proton-proton reaction rate due to meson exchange effects (M. Gari and A. M. Huffman, unpublished), predict a neutrino flux equivalent to 7 s.n.u. Our previous mixing hypothesis would be inadequate to resolve the present discrepancy, partly because the flux reduction factor is not large enough, and partly because the neutrino fluxes from s solar sources other than 8B should produce a counting rate equivalent to slightly more than 1 s.n.u., and the reduction in these fluxes due to mixing would be smaller due to the lower temperature sensitivity of the sources.
