On the connection between perturbation theory and new semiclassical expansion in quantum mechanics
It is shown that for the one-dimensional anharmonic oscillator with potential V(x)=ax2+bgx3+…=1g2Vˆ(gx), as well as for the radial oscillator V(r)=1g2Vˆ(gr) and for the perturbed Coulomb problem V(r)=αr+βgr+…=gV˜(gr), the Perturbation Theory in powers of the coupling constant g (weak coupling regime...
