So to the extent that neutrinos supply the energy for material ejection and set (Formula presented) in the ejecta, our nucleosynthesis considerations would also apply in the multi-dimensional scenarios of Ref. 16.

Note that the “just-so” (Formula presented) vacuum mixing solution to the solar neutrino puzzle is currently disfavored. However, this does not affect our discussion as the matter-enhanced (Formula presented) mixing solution works adequately in our scheme of evading the alpha effect for supernova r-process nucleosynthesis.

    • J. T. Peltoniemi hep-ph/9511323 has suggested that this scheme of neutrino transformation could circumvent the r-process constraints of Ref. 18 on neutrino mixing, and could possibly lower (Formula presented) Along these lines

    • H. Nunokawa, J. T. Peltoniemi, A. Rossi, and J. Valle, Phys. Rev. D 56, 1704 (1997), suggested that (Formula presented) and (Formula presented) transformation would cause (Formula presented) to reach the fixed point at (Formula presented). However, this will not occur in a rapid outflow (see Ref. 33). In addition, the simultaneous occurrence of (Formula presented) and (Formula presented) transformation envisioned by Nunokawa et al. could not circumvent the alpha effect discussed in the present work as their scenario would leave a significant (Formula presented) flux in the region where this effect would occur.
