We extend our recent works [ Int. J. Mod. Phys. A 38 (2023) 2350069-1] and
obtain one parameter (λ) family of rationally extended Dirac Lorentz
scalar potentials with their explicit solutions in terms of Xm​ exceptional
orthogonal polynomials. We further show that as the parameter λ→0 or −1, we get the corresponding rationally extended Pursey and
the rationally extended Abraham-Moses type of scalar potentials respectively,
which have one bound state less than the starting scalar potentials.Comment: LaTeX, 19 pages, 09 figures, 03 table
