Real and imaginary parts of scattering length a(k_0) as a function of incident wave vector k_0 at 24.5 kV/cm (red curve) 
and 26 kV/cm (blue curve). First column is wave vector k_0 (bohr^-1), second column is corresponding collision energy 
E_coll (K), third column is real part of scattering length alpha1 (bohr) at electric field 24.5 kV/cm, fourth column is 
negative imaginary part of scattering length beta1 (bohr) at same electric field. Fifth and sixth columns are real and
negative imaginary parts of scattering length (bohr) at electric field 26.0 kV/cm.
