The BCS integrand for diffusive scattering.

Parameters:

• q – Wavevector (1/nm).

• T – Absolute temperature (K).

• T_c – Critical temperature (K).

• Delta_0 – Superconducting gap at 0 K (eV).

• xi_0 – BCS coherence length (nm).

• ell – Electron mean-free-path (nm).

• lambda_L – London penetration depth (nm).

Returns:

The BCS integrand for diffusive scattering.
