Abstract

We present an interaction modeling for the relativistic spin-0 charged particles moving in a uniform magnetic field. In the absence of an improved perturbative way, we solve directly Kummer's differential equation including principal quantum numbers. As a functional approach to the nuclear interaction, we consider particle bound states without antiparticle regime. Within the approximation line to $1/r^4$, we have also improved the considerations of the $V(r)$$\neq$$0$ and $S(r)$$=$$0$ related to scalar and mass interactions. Moreover, we have founded a closeness for introduced approximation scheme for range of $0.5$ and $1.0$ $\mathrm {fm}$. In this way, minimal coupling might also yields analytically energy spectra. Within the spin-zero relativistic regime, we have considered the inverse-square interaction under uniform magnetic field and founded that the energy levels increase with increasing interaction energy (i.e, quantum well width decreases for given values). Additionally, energy levels increase with larger values of the uniform magnetic fields. The charge distributions is also valid for the central interaction-confinement space. Putting the approximation to spin-zero motion with $V(r)$$\neq$$0$ and $S(r)$$=$$0$, one can introduced solvable model in the 2D polar space.
