Stationary States of One Particle in 3 Dimensions

摘要: The 3-dimensional plane wave is the product of one-dimensional waves and kinetic energy sum contributions motions along x, y, z. More generally, problem separable into Cartesian coordinates if potential form $$\begin{aligned} V(x,y, z)=U_{x}(x)+U_{y}(y)+U_{z}(z) \end{aligned}$$ where \(U_{x}(x), U_{y}(y)\) e \(U_{z}(z)\) are arbitrary functions.
