WebDec 4, 2024 · In order to calculate the first-order correction to the ground-state energy of the quartic oscillator, use first-order perturbation theory. The potential energy is V ( x) = cx4. For this potential use the harmonic oscillator as the unperturbed system. Solve for the perturbing potential as well. Solution 7.26 Webgood states. To find the first order corrections to the energies, we need to find . 1. L SJ S + =+−. gg. ee ( ) (4.14) Since . J. is constant, L. and . S. are constrained to be coplanar with .
