Scattering and bound states of fermions in the modified Hulthén potential

In the present work the scattering of a fermion in the modified Hulthén potential is considered with a general vector and scalar and we solved the Dirac equation in the one-dimensional space. The transmission and reflection coefficients are reported. The bound-state solution is also given. The study shows the asymptotic behavior of the wave function in bound-state and scattering states solutions.
