Addendum — Power-like potentials: From the Bohr–Sommerfeld energies to exact ones

Numerical exploration suggests that for power-like potentials [Formula: see text] at [Formula: see text] the quantum WKB correction [Formula: see text], introduced in [J. C. del Valle and A. V. Turbiner, Int. J. Mod. Phys. A 36, 2150221 (2021)], has the form [Formula: see text], where [Formula: see text] is the shifted quantum number N. The leading coefficient in the [Formula: see text]-expansion is found to be a simple analytic expression, while several subleading terms are found numerically with high accuracy.
