Abstract
Energy levels of the Schrödinger equation for a double-well potentialV(x, y; Z x 2, Zy 2,λ) = −Z x 2 x 2 -Z y 2 y 2 +λ[a xx x 4 + 2a xy x2y2 +a yy y 4] in a two-dimensional system are calculated using the Hill determinant approach for several eigenstates and over a wide range of values of the perturbation parameters (λ, Z x 2,Z y 2). Some of the results calculated by the Hill determinant approach are compared with those results produced by the inner product technique.
