Query: Pairing Theory of the Wigner Cusp   Conclusions: (1) Calculations with an RPA correction added to the BCS pairing
correction conventionally employed in Nilsson-Strutinskij calculations account
well for the variation with A of the pattern of masses near N=Z. (2) The RPA
correction is insignificant for reproducing the doubly even masses and hence
for the shape of the Wigner cusp. (3) It is important, however, that the
macroscopic (liquid drop) symmetry energy be proportional to T(T+1). (4) This
form of the macroscopic symmetry energy is understood microscopically, in terms
of the RPA, to result from the nuclear superfluidity. (5) The variation of the
shape of the Wigner cusp is dominated by shell effects. (6) The RPA correction
significally reduces the T=0 binding in doubly odd nuclei, thus reducing the
required pair coupling constant.
