Definition:

   
     First, the parameters are used directly to approximate spatial
     averages of  spherical Bessel functions over the electronic wave
     functions of unpaired  electrons of the given atom type as a
     function of s = sin(theta)/lambda.
     <jn(s)> = [A1*e^(-a2*s^2) + B1*e^(-b2*s^2) + C1*e^(-c2*s^2) +
     D]*[1 if n=0, s^2 if n=2,4,6]
     The <jn(s)> are then combined to determine the spin and orbital
     contributions to the magnetic form factor of the atom.  The "e"
     parameter is a measure of error in the approximation.
