  Recently, it has been shown that the generalized symmetric Woods-Saxon
potential energy, in which surface interaction terms are taken into account,
describes the physical processes better than the standard form. Therefore in
this study, we investigate the scattering of Klein-Gordon particles in the
presence of both generalized symmetric Woods-Saxon vector and scalar potential.
In one spatial dimension we obtain the solutions in terms of hypergeometric
functions for spin symmetric or pseudo-spin symmetric cases. Finally, we plot
transmission and reflection probabilities for incident particles with negative
and positive energy for some critical arbitrary parameters and discuss the
correlations for both cases.
