I need a more complete solution for Owen and Scalapino energy gap shift.?

Question

I mean the energy gap shift calculated by Owen and Scalapino in superconductor materials in[Phys.Rev.lett.28,1559(1972)].i need a solution like the Fig.1(b) of this paper which includes more graphs for a larger range of n,or more n values.is there a paper which can help me for this or a computer program to solve equation(7) of this paper?

Answer 1

Try Mathematica or Maple.
