COMMENTS

The geometric mean of a large N value in Planck square mass units in the midpoint isospin symmetry transition where exists superposition of protonic-neutronic degenerate matter in a spherical gravitationally collapsing system.

The sequence data corresponds to the Codata 2010 value alpha = 0.0072973525698 (= A003673, as of today). - M. F. Hasler, Feb 02 2014
