"Solve the Dirac equation and return g(r=r_max)"
"Solve the Dirac equation and return g(r=r_max) for given scalar and vector potentials where
κ is the generalized angular momentum,
M is the mass in MeV/c2,
E in the energy in MeV,
S(r) & V(r) are functions corresponding to scalar and vector potentials in MeV,
r_max is the outer boundary,
r_min (=r_max/1000) is inside boundary which cannot be 0 due to the centrifugal term."
