Figures’ Captions: Figure 1: Shows the effect of V$_{eff}$ ( ϕ ) = − a $^{2}$e iϕ on the probability density as the coupling parameter a increases for n = 1 , ℓ = 0 = m . Figure 2: Shows the effect of V$_{eff}$ ( ϕ ) = − a $^{2}$e iϕ on the probability density as the coupling parameter a increases for n = 2 , ℓ = 0 = m . 20
