Historical pseudo simplified solution of the Dirac-Coulomb equation
Ruida Chen
One of the simplified solutions of the Dirac equations with the pure Coulomb potential given in a paper published in 1985 is pseudo. The original paper solved the Dirac equations b…
Unheeded pseudo solution of Dirac-Coulomb equations with an indirect transformation of functions
Ruida Chen
We open out one of incorrect solutions of the Driac equation in the Coulomb field given in a published paper. By introducing a transformation of function, the paper transformed the…
Established pseudo solution of second-order Dirac-Coulomb equation with position-dependent mass
Ruida Chen
We show that one of exact solutions of the second-order Dirac-Coulomb equation were pseudo. In the corresponding original literature, it was considered that the mass of the electro…
New exact solution of Dirac-Coulomb equation with exact boundary condition
Ruida Chen
It usually writes the boundary condition of the wave equation in the Coulomb field as a rough form without considering the size of the atomic nucleus. The rough expression brings o…
